#03 Testing grayscale

Here’s a way to see faults in a design. Check the grayscale conversion. All touching colors should have a 30% differential – especially for text. If something can’t be read in grayscale (no color cues) adjustments need to be made.

There are various ways to convert to grayscale. In this case, I used GIMP (for Linux) and under COLORS used the Desaturation tool to remove all color. If I run over it with the color picker, it gives me percent grayscale. I also use Photoshop to do the same trick but just a little different. Again, the color picker will show percent grayscale in a control panel.
