Dear list
I need to typeset a book for kids wich contains texts where each letter is assigned a fixed color, for example:
A - - > red; B - - > blue; ... Z - - > green.
What would be the best way to do this? TIA.

There's more ways to do this but here is one:
(1) make a file: colorfont.lfg:
return { name = "coloralphabet", colorschemes = { default = { [1] = { "a", "e" }, [2] = { "i", "o", "u" }, }, whatever = { [1] = { "65:90" }, [2] = { }, [3] = { }, [4] = { "97:122" }, } } }
There is some more possible but this wil do ...
(2) You define a font with these goodies attached:
\setupbodyfont[plex,10pt]
\definefontfeature [MyFeaturesA] [default] [goodies={colorfont},colorscheme=default,liga=no]
\definefontfeature [MyFeaturesB] [default] [goodies={colorfont},colorscheme=whatever,liga=no]
\definefont[MyFontA][Serif*MyFeaturesA] \definefont[MyFontB][Serif*MyFeaturesB]
(3) and use it this way:
\starttext
\setfontcolorscheme[1] {\MyFontA \samplefile{tufte}}\par \setfontcolorscheme[2] {\MyFontA \samplefile{tufte}}\par \setfontcolorscheme[3] {\MyFontA \samplefile{tufte}}\par
\page
\setfontcolorscheme[1] {\MyFontB \samplefile{tufte}}\par \setfontcolorscheme[2] {\MyFontB \samplefile{tufte}}\par \setfontcolorscheme[3] {\MyFontB \samplefile{tufte}}\par
\stoptext
Now, this is pretty (more than a decade) old functionality from early days of mkiv/luatex when it was used for some tracing (by Idris) and it still works (surprise).
Today I would definitely use more recent trickery. If there is real demand for this I can have a look at it, after all it's "kind of fun" (as is most of font stuff).

Thank you, Hans for your answer.
I tried your code and it works fine. But where do the color schemes default and whatever come from? How can they be changed?
Best regards

defauls is defined in the example .. colorshemes have numbers:
\definecolor[colorscheme:1:1][s=.75] \definecolor[colorscheme:1:2][r=.75] \definecolor[colorscheme:1:3][g=.75] \definecolor[colorscheme:1:4][b=.75] \definecolor[colorscheme:1:5][c=.75] \definecolor[colorscheme:1:6][m=.75] \definecolor[colorscheme:1:7][y=.75]

Hi, again
With the suggestions you gave I managed to obtain the functionality I need, almost. Somehow letters with accents like á ã é ó õ and also ç don't get the same color of the base letters given in the colorfont.lfg below:
return { name = "coloralphabet", colorschemes = { default = { [1] = { "A", "a", "á", "ã", "å", "à", "ä" }, [2] = { "b", "B" }, [3] = { "c", "ç", "C", "Ç" }, [4] = { "d", "D" }, [5] = { "e", "E" }, [6] = { "f", "F" }, [7] = { "g", "G" }, [8] = { "h", "H" }, [9] = { "i", "í", "ì", "I", "Í", "Ì" }, [10] = { "j", "J" }, [11] = { "k", "K" }, [12] = { "l", "L" }, [13] = { "m", "M" }, [14] = { "n", "ñ", "N", "Ñ" }, [15] = { "o", "ó", "õ", "ö", "O", "Ó", "Õ", "Ö" }, [16] = { "p", "P" }, [17] = { "q", "Q" }, [18] = { "r", "R" }, [19] = { "s", "S" }, [20] = { "t", "T" }, [21] = { "u", "ù", "ú", "ü", "U", "Ù", "Ú", "Ü" }, [22] = { "v", "V" }, [23] = { "w", "W" }, [24] = { "x", "X" }, [25] = { "y", "Y" }, [26] = { "z", "Z" }, }, } }
The MWE follows below:
\setupbodyfont[plex,22pt]

glyph names ... "oacute" etc as used in plex
Greetings
Marcus Vinicius
Ok, after changing the glyph names in colorfont.lfg things run smoothly but for six glyphs:
uacute, ucircumflex, udieresis, Uacute, Ucircumflex, Udieresis
Have I hit a bug?

Some font oddness ... use
"uhungarumlaut", "Uhungarumlaut", 0x1DC, 0x144, 0xFA, 0xFB, 0xFC, 0xDA, 0xDB, 0xDC },
Maybe use numbers for all instead. All is revealed by:
\usemodule[fonts-complete] \setupbodyfont[6pt] \starttext \ShowCompleteFont{name:IBMPlexSerif}{10pt}{1} \stoptext
I'll send you a 'context' way of doing it ... .
