CAD tip # 13597:

Select the desired color by dragging the mouse in the palette swatch or enter it numerically, e.g. using RGB values (0-255), hexadecimal color code (e.g. from the web) or select the desired hue in the RAL or AutoCAD ACI color index select-box. You can also use the alpha channel, transparency (Alfa).

After selecting a color, the values of its color components in other color models (e.g. C-M-Y-K) are displayed. The so-called "long" RGB value used internally in Office applications, in Navisworks, in VBA, or e.g. in the UI color settings in AutoCAD is also displayed (in italics) - see Tip 3088.

In addition, similar colors from the Pantone palette are listed - within the range of the so-called color distance (tolerance).

Note that not all color hues have a direct equivalent in another color model. Colors in the Pantone and RAL palettes are certified on the official swatches - the displayed hues and RGB values are just their approximations.
