Hi,
I have designed a cube and gave colors to it.
In Preview, it is showing the exact. But when I have performed Rendering,
the colors are not appearing.
I am new to OpenSCAD. How can I solve it ?

Below is my code for it.

cubes_per_row = 9;a=20;b=10;for(y=[0:cubes_per_row]){
for(x=[0:cubes_per_row])    {    translate([ax,a*y,0])
color([(255)/255,    ((x+1)70)/255 + ((x+1)70)/255sin(x),
((x+1)120)/255cos(x)    ])        cube([a,a,b]);          }}

and want to know is there any simple program to design a chess plate
showing different colors in every boxes in it ?

"changing the colors only works in Preview mode (F5); render mode (F6) does not currently support color."
Your question about designing a chess board, consider Tinkercad, a free web-based 3D modeling program that uses primitives, drag and drop interface and would easily generate that which you require. For aligning the individual blocks, use the workplane feature to attach a plane to a previous row or column of blocks and align to zero for that plane.

Your post adds useful information, referencing blender. Colors in blender are referred to as textures. A search of the 'net for "openscad texture mapping" provides a number of resources that may be of value to you. One of the links is a thingiverse item which has in the description the suggestion to add colors, implying that it is one of the features of texture mapping that is supported.

Thank you for the information.
I have already tried,According to the wiki entry:OpenSCAD User Manual/First Steps/Changing the colour of an object - Wikibooks, open books for an open world
But I am not getting creating the multiple blocks with multiple colors.
And as you said I have tried using Tinkercad, but when I have exported its obj. file or stl. file into Blender the colors are not appearing.
