Join John Derry for an in-depth discussion in this video Using the Color Picker Heads-Up Display, part of Photoshop CS5: Painting with the Mixer Brush.
Along with the marks made by a brush, color is a highly expressive component of painting.…Fortunately, there are multiple ways to access color in Photoshop.…In this video, we will look at how to quickly call up various color selection tools.…Now you certainly have keyboard shortcuts available, and I will explain those…as well, but once again, I'm relying on the elegance of the control surface of…the Wacom to do the heavy lifting for me.…
The first tool I want to introduce you to is what's called the HUD Color Picker…- HUD is short for Heads Up Display - and this is a new color picker that…enables you to get to a pretty elegant solution here.…I will show it to you.…Here it is, and in a moment, I will show you the various ways you can configure this.…But this lets me, right onscreen, select from both hue and saturation value, to…select a color that I can then paint with.…
That's a very valuable way to go about doing this.…You can control how the appearance of this looks in the Preferences panel, under General.…

Q: What factors affect how well the mixer brushes in Photoshop perform? Does document size (i.e. 72dpi vs. 240dpi) affect the performance of the brushes? How can I maximize brush performance?
A: The recordings for this tutorial were generally done at a standard screen resolution, but a real-world situation will often require higher resolutions. For example, offset printing generally dictates files at 300ppi (pixels per inch). Inkjet printing is often discussed in terms of 240ppi. For web-based viewing, imagery at 72ppi is considered acceptable. You can easily determine the pixel resolution of an image by multiplying the size in inches by the above ppi (pixels per inch) factors.
Let's use a typical real-world size as an example: 20" X 24". This is a common photographic print and frame size.
72ppi = 1440p X 1728p = 2,488,320 pixels
150ppi = 3000p X 3600p = 10,800,000 pixels
300ppi = 6000p X 7200p = 43,200,000 pixels
Note that each of these resolution factors quadruples the total pixel count.
It is the amount of pixels being manipulated that dictates both application and brush performance. With this in mind, we can state that performance decreases as image pixel size increases. There are three primary factors that affect an application's ability to handle large pixel-based manipulation.
