In my copious spare time I like to design electronic circuits. I am by no means an expert, but I know enough to be dangerous. Inspired by Ben Eater's "Let's build a video card!" page [1], I started thinking about a video circuit for a 6-bit controller so it could drive a small touch-screen display.
As part of that design process I came up with a very simple 6-bit color model. It sort of reminds me of the good 'ol 8-bit days when the 16 colors of the Commodore 64 and TI-99/4(a) were considered amazing.
The block below shows the different colors as a grid. And then there are a couple of pictures which have been modified to use that palette.
And here are the pictures. They're not horrible when you consider the target for these images is a process controller that uses a touch-screen for a simple user interface and the 6-bit color scheme is extremely näive.
