gradient colors & styles

[bajcik kolos math uni lodz pl]

Hello,

I'm working on a swapping system symulator (in gtk+2.0). I was using
widget->style to plot any symbols till now.

Now I need to show a value in a range. I can declare a GdkGC
*table[256], but which colors will be suitable with every style?

I could solve it in two ways:

1. Use ONLY custom colors (for symbols and gradient) and forget GtkStyle
2. Use style->white and style->black to generate a table:
    for (i=0; i<256; i++)
    {
       table[i].red   = style->white.red   * i / 256 + style->black.red   * (256-i) / 256;
       table[i].green = style->white.green * i / 256 + style->black.green * (256-i) / 256;
       table[i].blue  = style->white.blue  * i / 256 + style->black.blue  * (256-i) / 256;
    }

What should I do to have nice looking gradient in every style?
