Welcome to the world of Hex Codes and RGB values. It

might appear a strange area at first sight, but once you

are a little more familiar with it you will find it a safe and

harmonious place to be. For it is a simple world in which

everything is done as agreed and so everything is

related in a constant way as you might encounter already

in the picture below. And most certainly it is colourful.

The RGB values range from '0' to '255', meaning a total

of 256 because the value '0' is here not nothing, but

simply the value named '0'. Note here the difference with

colour perception in the craft of printers who see black

and white not as colours but 'just' as regular ink and

paper.

For the Hex Codes the numbers 0 - 9 and the letters a - f

are used in pairs, such as 'aa', 'B0', '1C', 'DD', 'ee', '2f',

'33', '45', etc.

The most striking values of Hex Codes that appear in

pairs of equal symbols and their corresponding RGB

value produce a sequence with a difference of 17 as is

pointed out in the following picture:

15 striking values for Hex and RGB         HEX v RGB v         00 0    +11 +17   11 17   +11 +17   22 34   +11 +17   33 51   +11 +17   44 68   +11 +17   55 85   +11 +17   66 102   +11 +17   77 119   +11 +17   88 136   +11 +17   99 153   +11 +17   AA 170   +11 +17   BB 187   +11 +17   CC 204   +11 +17   DD 221   +11 +17   EE 238   +11 +17   FF 255

Combinations of these equal pairs into hex codes of

three pairs produce than also the very web-safe or

web-smart colours. The range from dark to light follows

the 'higher' number or letter as is shown in the following

most simple colour sequences:

Hex code R-G-B   #000000 (Black) 0-0-0   #111111 17-17-17   #222222 34-34-34   #333333 51-51-51   #444444 68-68-68   #555555 85-85-85   #666666 102-102-102   #777777 119-119-119   {#808080 (Gray)} 128-128-128   #888888 136-136-136   #999999 153-153-153   #AAAAAA 170-170-170   #BBBBBB 187-187-187   #CCCCCC 204-204-204   #DDDDDD 221-221-221   #EEEEEE 238-238-238   #FFFFFF (White) 255-255-255

or as in the following 'glossy' (!) example:

Hex code R-G-B   #112233 17-34-51   #223344 34-51-68   #334455 51-68-81   #445566 68-81-102   #556677 81-102-119   #667788 102-119-136   #778899 119-136-153   #8899AA 136-153-170   #99AABB 153-170-187   #AABBCC 170-187-204   #BBCCDD 187-204-221   #CCDDEE 204-221-238   #DDEEFF 221-238-255

However this kind of graduation is seldom used.  An

alternately 1 and 2 variation (alternately 2 and 3

difference) in following RGB values (and so hex code

values) seems to be preferred for a much finer gradation

or variation of lightness as can be observed for instance

in the following part of the sequence of greys:

name - hex code R-G-B   gray 74 - #BDBDBD 189-189-189   gray 75 - #BFBFBF 191-191-191   gray 76 - #C2C2C2 194-194-194   gray 77 - #C4C4C4 196-196-196   gray 78 - #C7C7C7 199-199-199   gray 79 - #C9C9C9 201-201-201   gray 80 - #CCCCCC 204-204-204

which would look further refined in one 'step'

successively in detail, for instance:

name - hex code R-G-B   gray 74 - #BDBDBD 189-189-189                  #BEBEBE 190-190-190   gray 75 - #BFBFBF 191-191-191   (silver)    #C0C0C0 192-192-192                  #C1C1C1 193-193-193   gray 76 - #C2C2C2 194-194-194

to show that a finer gradation would hardly produce a

visible difference in a short range.

In the mean time it has also become fully clear how the

the Hex Code is successively built up.

Nevertheless it may be timesaving or useful otherwise to

use the following tool to calculate the RGB numbers of a

specific Hex Code (here no '#' or ',' input) or vice versa,

if you would like to do so:

Hex Code R G B R G B Hex Code

Usually a Hex Code or RGB value follows, so to say, a

chosen, picked up or even a created colour. At least

colours are constructed on basis of Hex Codes or RGB

values. Therefore here the opportunity is taken to

present a few spectra with such colours, which -for that

matter- found also their use, as limited as they are, at

this web site.

A first micro spectrum is one that has already three

known colours:

name Hex Code R G B steelblue   #236B8E 35 107 142 olivedrab   #6B8E23 107 142 35 sienna   #8E6B23 142 107 35  and so just deserves some completion with the colours: antonviolet   #8E236B 142 35 107 kennardpurple   #6B238E 107 35 142 forestherbgreen   #238E26 35 142 107

A next one, regarding particular RGB values, is already

at beforehand very obvious, but nevertheless interesting

to present:

name Hex Code R G B foxdarkred   #6F0B0B 111 11 11 amlotviolet   #6F0B6F 111 11 111 sannyblue   #0B0B6F 11 11 111 miesaquamarine   #0B6F6F 11 111 111 gonnygreen   #0B6F0B 11 111 11 darkolive   #6F6F0B 111 111 11 thijgray   #6F6F6F 111 111 111 miesblack   #0B0B0B 11 11 11

or also than:

name Hex Code R G B amlotred   #DE1616 222 22 22 lillypurple   #DE16DE 222 22 222 amlotblue   #1616DE 22 22 222 michyturquoise   #16DEDE 22 222 222 miesgreen   #16DE16 22 222 22 kennygold   #DEDE16 222 222 22 gray 87   #DEDEDE 222 222 222 amlotblack   #161616 22 22 22

which amusement could continue for example with some

dark colours as:

name Hex Code R G B jackblue   #0C2238 12 34 56 verydarkviolet   #7B2D43 123 45 67 panwoodsgreen   #0D3909 13 57 9 bettybrown   #874F0B 135 79 11 rumchocolate   #774B1F 119 75 31 greentan   #412B15 65 43 21

So far for now these spectra of colours that are

composed with regard to their specific RGB values.

The next spectra than are composed with regard to

specific Hex Codes. The first one is obvious:

name Hex Code R G B foxred   #AA1111 170 17 17 foxred 2   #BB2222 187 34 34 foxred 1   #CC3333 204 51 51 twentesalmon   #DD4444 221 68 68 brabantsalmon   #EE5555 238 85 85 seattlesalmon   #FF6666 255 102 102 madelorchid   #FF66FF 255 102 255 madelorchid 1   #EE55EE 238 85 238 madelorchid 2   #DD44DD 221 68 221 madelorchid 3   #CC33CC 204 51 204 eddypurple   #BB22BB 187 34 187 eddypurple1   #AA11AA 170 17 170 norablue   #1111AA 17 17 170 norablue2   #2222BB 34 34 187 norablue1   #3333CC 51 51 204 lillyblue2   #4444DD 68 68 221 lillyblue 1   #5555EE 85 85 238 lillyblue   #6666FF 102 102 255 neonteal   #66FFFF 102 255 255 jadeblue light 1   #55EEEE 85 238 238 jadeblue light   #44DDDD 68 221 221 jadeblue   #33CCCC 51 204 204 jadeblue 1   #22BBBB 34 187 187 jadeblue 2   #11AAAA 17 170 170 herbgreen 3   #11AA11 17 170 17 herbgreen 2   #22BB22 34 187 34 herbgreen 1   #33CC33 51 204 51 herbgreen light   #44DD44 68 221 68 herbgreen light 1   #55EE55 85 238 85 parakeetgreen   #66FF66 102 255 102 gonnyyellow   #FFFF66 255 255 102 michygold   #EEEE55 238 238 85 amlotgold   #DDDD44 221 221 68 antongold   #CCCC33 204 204 51 antongold 1   #BBBB22 187 170 17 antongold 2   #AAAA11 170 170 17

but the following one needs perhaps a little explanation.

Again pairs of same letters are chosen, but for the

variation of numbers the number '15' has been taken.

This, of course, because it is the author's lucky number

ever since he was seven and a half years old, but more

over since the total of symbols (16) used for Hex Codes

in the light range is fifteen. Etc., etc. Anyway, this choice

produces the following harmonious partial spectra:

name colour Hex Code R G B thijred 4   #AA1515 170 21 21 thijred 2   #BB1515 187 21 21 thijred 1   #CC1515 204 21 21 kennyred    #DD1515 221 21 21 rosered   #EE1515 238 21 21 redrose   #FF1515 255 21 21

and added to these are also:

name colour Hex Code R G B darkfoxred   #6F0B0B 111 11 11 royalred   #990000 153 0 0 thijred (thijred 3)   #AE1515 174 21 21 gogored   #C01515 192 21 21 gonnypurple   #AE15AE 174 21 174 nobleblue   #1515AE 21 21 174 tealblue   #15AEAE 21 174 174 herbgreen   #15AE15 21 174 21 thijgold 4   #AEAE15 174 174 21 gogogold   #C0C015 192 192 21 kennygold   #DEDE16 222 222 22

to form the main harmonious thij spectrum of which, as it

matters regarding the design of this site, those parts with

respect to the red - and gold are demonstrated as

follows in respective contrasts:

A few following examples show these colours 'in action':

HtT 'thijgold 2' 'thijred' HtT 'thijred' 'thijgold 2' HtT 'gogogold' 'thijred' HtT 'thijred' 'gogogold' HtT 'thijgold 4' 'thijred' HtT 'thijred' 'thijgold 4'

Although these combinations do fine in contrast, still a

'gold' colour with a red tone in it is preferred for more

harmony above these more greenish or yellowish 'gold'

variations. Therefore a next 'gold' species has been

created:

HtT 'oldthijgold' 'thijred' HtT 'thijred' 'oldthijgold'

All these combinations do fine in smaller areas on the

screen. In larger ones, however, less light in the 'red' as

background is preferred. So often in that case the

following combination deserves the preference:

HtT 'oldthijgold' 'royalred' HtT 'royalred' 'oldthijgold'

For the same reason, but also to enhance the contrasts,

a 'silver' variation -especially harmonious in combination

with a radiant 'blue'- with more white "light" (so mixed

with some blue than, the answer to a previous hidden

question) in it was found:

name colour Hex Code R G B argent   #E7F2FD 231 242 253 silver   #E6E8FA 230 232 250 silver   #C0C0C0 192 192 192   'Argent' is than a colour that closes the spectrum   sequence that begins with:     ravenblack   #0B1621 11 22 33 donarblack   #16212C 22 33 44   and that goes on this way (RGBv, d 11), arriving at: lightslaygray   #4D5863 77 88 99   only to continue to the final section: argent 5   #B0BBC6 176 187 198 argent4   #BBC6D1 187 198 209 argent 3   #C6D1DC 198 209 220 argent 2   #D1DCE7 209 220 231 argent 1   #DCE7F2 220 231 242 argent   #E7F2FD 231 242 253

and some examples of combinations are finally:

argent 'thijgold 4' 'argent' argent 'thijred' 'argent' argent 'nobleblue' 'argent' argent 'royalred' 'argent' argent 'oldthijgold' 'argent'
