Can we color the Excel sheet cells with any desired color through VBA (using
RGB function for example) or we are restricted with the color set that we
can use from the worksheet?

Marwan,

Excel has a color pallet of 56 colors -- everything in Excel
(Fonts, Backgrounds, Charts, etc) must be one of those 56 colors.
However, you can put any of the 16 million RGB colors in to the
pallet. You can define your own color pallet using code like

ThisWorkbook.Colors(56) = RGB(123, 45, 67)

This defines color 56 to be the color value produced by RGB(123,
45, 67). You can assign any or all of the 1 to 56 Color array
elements to whatever colors you desire. When you change a color
value in the Colors array, all elements (text, backgrounds, etc)
that use that ColorIndex will use the new color value. For
example, if you use code like

Range("A1").Interior.ColorIndex = 42

you are using Colors(42). If you then change Colors(42) to
another color with code like

ThisWorkbook.Colors(56) = RGB(123, 45, 67)

then A1 will have the new color.

So in summary, yes, you are limited to 56 colors, but each of
those colors can be any of 16 million available colors.
