The Select Color dialog is used when you want to change the color for a course object or a graphics object.  

This dialog lets you choose between colors in the CMYK color space or the RGB color space.

You can enter a value for C, M, Y, K as a percentage (0% - 100%)  When all four values are 0, the color is white.

You can enter a value for R, G, B in the range 0 - 255.  When all three values are 0, the color is black.  When all three values are 255, the color is white.

When you switch between RGB and CMYK, Condes keeps the resulting color as close as possible to the existing color.  However, the translation from RGB to CMYK and vice versa is not reversible, so if you switch between the two color spaces, the color changes slightly.

When you use RGB colors, you can either enter the RGB values in the edit fields, or you can use the "hexagon" palettes and the luminance bar to select a color.
