Pick a text color that matches the images in your slide

As you can see from the examples above, slides look nice when the text color goes well with the colors in the background image. To pick a color from the image, select the text, and drag the 'text color' icon in the Colors Lab panel to the color in the image that you want to use for the text. You can see a live preview as you drag the icon.
If you want to use a color that is not in the image but goes well with the image, drag the 'main color' icon to pick a dominant color from the image. When you do that, Colors Lab will show you a selection of colors that goes well with the picked color. To pick any of those colors, select the text as before, and the drag the 'text color' icon to the suggested color you want to use. Here's how it is done:

Colors Lab comes with the free PowerPointLabs add-in and works for both PowerPoint 2010 and 2013 on Windows. You can use it to pick colors from anywhere in the screen, not just from the slide.

Pick colors for your PowerPoint slides from anywhere in the screen

The Colors Lab feature (included in PowerPointLabs) allows you to apply colors to text and shapes on any of your slides. To do so, first select the element to change by clicking on it within the slide.

The Colors Lab can change the color of text, as well as the border outline color and background fill color of shapes. This can be done by clicking and dragging from the appropriate button to the color you wish to use.
It can be used to pick colors from images in the slide, and even from outside PowerPoint. This is handy for copying a color from other websites.

 

Another cool thing about the Colors Lab is that it can help you pick good color combinations. If you change the main color of the Colors Lab (by dragging the color box on top), Colors lab tells you what are the other colors that can go with that color.
