for i : 1 .. 256 %there are only 256 pre-determined colours
colour (i) % makes number the same colour as the colour
put i .. % puts number
put " " .. % makes a space
end for

Actually there are only 255 colors. And this way may be better because it deals with the fact that by just adding a space you will eventually split the numbers between two lines.
Turing:
for i : 1 .. 255
    color (i)
    put count : 4 ..  % note the : 4. it keeps it even and lined up.
end for

You got the right idea tho.

(Your code does not run by the way. Replace count with i.)


Believe it or not, there are 256 colours. I like it this way:

Turing:
for i : 0 .. 255
    colourback (i)
    put i : 5 ..
end for

% try this with the code
for i : 1 .. 255
drawfillbox (round (maxx / 255) * i, 0, round
(maxx / 255) * i + 2, maxy, i)
end for

Wouldn't the best reference be to simply use maxcolour instead of 255?
It would improve readability, as well as eliminating assumptions....although I guess the max number of colours remains constant

Sorry i forgot to put the i there and i also forgot about 0 being white.

To be honest, I prefer finding the right colour with a mouse, rather than looking through 255 numbers.

code:
View.Set ("graphics:max,max")
var x, y, b : int
var width : int := 4
for i : 0 .. 255
    for i2 : 1 .. width
        Draw.Line (i * width + i2, 0, i * width + i2, maxy - 16, i)
    end for
end for
loop
    Mouse.Where (x, y, b)
    x -= 1
    if x > 0 and x < maxx then
        locate (1, 1)
        put "colour #", floor (x / width)
        Draw.FillBox (120, maxy - 14, 150, maxy, floor (x / width))
    end if
    delay(30)
end loop
