I am terribly sorry but need some help.
I am not able to create blue using COLOR command
COLOR 255 255 0 0 0 is red
255 0 255 green
0 0 0 black
and 0 255 255 instead of blue is light green.
What is the problem?

Hi,
the color system in use is RGB, which is a shortcut for red, green, blue.
The first three numbers after a color command represent the red, green and blue channel respectively. The values should always be in the [0..1] interval, the max. value of [255] is used for UV-coordinates, not colors. Look up the standard "world"-scenery for some examples.
I haven't found any use for entry four and five. In case you have ever used any modeling/rendering software, you'd assume it is either an ambient, emissive or specular intensity, but no luck so far. So I'll leave them at zero all times as they're not needed anyway.
Make sure that lighting is ON, and you'll get:
1 0 0 - red
0 1 0 - green
0 0 1 - blue
0 1 1 - cyan
1 0 1 - magenta
1 1 0 - yellow
0 0 0 - black
1 1 1 - white
regards
