ეს ნამუშევარი მისი ავტორის Janke მიერ გადაცემულია საზოგადოებრივ დომენში. ეს მოქმედებს მთელი მსოფლიოს მასშტაბით. ზოგიერთ ქვეყანაში ეს შეიძლება იურიდიულად შეუძლებელი იყოს, ასეთ შემთხვევაში: Janke უფლება მისცა ნებისმიერს, რათა გამოიყენონ ეს ნამუშევარი ნებისმიერი მიზნით, ყოველგვარი წინაპირობის გარეშე, თუ რაიმე პირობა კანონის მიერ არ არის მოთხოვნილი.

The human eye can distinguish about 10 million different colors, but most of them lie outside the gamut of this image.

Created with the following very short program written in Chipmunk Basic:

10 for x = 0 to 999
20 for y = 0 to 999
30 z = int(y/100)*10+int(x/100)
40 graphics color x,y,z ' x=red y=green z=blue
50 pset x,y
60 next y,x

The value for red changes cyclically in the left-right axis, in ten periods of a sawtooth wave, going from 0 to 100% in 1% increments per pixel; the value for green changes cyclically in the vertical axis in the same way; while the value for blue changes by 1% in each small, 100 by 100 pixel square, moving across then down, as seen when the channels are separated below. Imagine putting all the 100 by 100 pixel squares on top of each other — you would then have a cube, 100 px each side, with R, G, and B along the x, y, and z coordinates, each changing 1% for every step.

In the above example blue changes by 1% in each small square of 100 by 100 pixels, but it could just as well have been red or green. Below are three squares, the top has red changing in each small square, the middle one changes are in green and the bottom is blue. Each of the large squares contain the same set of colors, but in different arrangements.
