Different blue HP 50g model variants

[Brian D]

Convert the images to grayscale to see how a different brightness for each shifted function can be useful. For example, imagine taking the 50G but change the bright white shift key and labels into a light gray or other light color. This makes the primary key functions stand out, and the shifted keys would be a bit dimmer for one shift function, and dimmer still for the other.

The 15C does this with white, gold, and blue, each of a different brightness level.
