One of the new features in Corel® Painter™ 12 is the Temporal Colors Palette. Here is some information about it which I have extracted from one of the lessons in my new Corel Painter: Get up to speed class at lvsonline.com
The Temporal Colors Palette
The Temporal Colors Palette is a small color picker which floats in the Document Window. You can use it to choose colors on the fly or to match colors to your image while painting. To call the Temporal Colors Palette, use the following shortcut key combination:
Ctrl+Alt+1 or Cmd+Option+1
As you can see, the Temporal Colors Palette contains many of the same settings as the Color panel. It's very handy when you're working on a particularly large image and need as much of your workspace real estate as possible. You can hide the other color panels, and just bring up the Temporal Colors Palette as needed. Another excellent use for it is when you want to find a color to add to your painting which will match, harmonize, or contrast nicely with the other colors. To do so, you would move the Temporal Colors Palette over the image until you find the color you wish to match and/or use.
If you find that the Temporal Colors Palette pops up in inconvenient places, it's very easy to move. Just hold your cursor over any blank area inside the Hue Ring, left-click, and you can move it any where you wish.
The Temporal Colors Palette can also be resized. Simply hover your cursor over the outer circular edge until it turns into a 4-headed arrow, then drag out from the ring to enlarge, or drag in toward the ring to make it smaller:
This handy tool is just one of the many new features you will find in Corel® Painter™ 12.
