define a color by entering a value

[JonM]

In Corel Draw I could make a color by entering values for instance :
Red = 10
Green = 99
Blue = 11
Result a named colour.

How to do in Designer Pro X or PGD ?

If there's a specific color you have in mind that you need the HEX values for, there's a site called HTML Color Codes that has a huge list of the 6-digit values.
