The Color Samples Panel.
The Color Samples Panel is stuck to the right hand side of the ArtRage Window, above the Color Picker. It is used for storing colors that you may want to use later. By default, it is empty, but you can add colors easily.
To add a color to one of the empty holes, just click it. When you do so, the current color will fill that hole, think of it like a little pot of ink.
Now, whenever you want to use that color again, just click its little pot and the current color will change to match it. If you want to store more colors, click in the other holes. There will always be at least one hole free for you to add color to. If you have so many colors the panel can’t fit on the side of the window properly, it will extend to make space for more.
If you wish to remove a color you have assigned, just right click in the pot and it will empty itself out.
You can also load and save combinations of color samples using the menu, accessed from the arrow at the top of the panel.
By clicking and dragging the green grip on this panel, you can drag it up and down the window’s edge. If you just click it, the panel will retract. If you don’t plan on using the Tool Settings, just retract it and leave it shut.
