RGB Color

You can select an RGB color for a hatch.

You can freely select any RGB color by clicking on the color gradient in the dialog box. The selected color has a certain hue and saturation. You can adjust the color's luminosity with a slider.

Hue
Select the hue from the color gradient area in the horizontal direction.
Saturation
Select the saturation from the color gradient area in the vertical direction.
Luminosity
You can select the color's luminosity by dragging the slider with the cursor in the direction of the Y axis in the dialog box. Black and white are at the extremities of the slider.
If you adjust this property to completely black or white, changing the color's hue or saturation will have no effect.
Add to Custom Colors
Click this button to save the selected color in a separate Custom colors menu. You can define 16 different custom colors which are saved in the user/CUSTOMCOLORS file.
