Color Cell Converter

What is this?

I watched this video: https://www.youtube.com/watch?v=Tfh0ytz8S0k ('How "oldschool" graphics worked Part 1 - Commodore and Nintendo' by "The 8-bit Guy")

I thought it was interesting and I wanted to make something, for practice with Go.

How to use

go install or go build

color-cell-converter -i inputFile -o outputFile ...

Problem(s)

• Green tends to be sparse in the converted images.
• Pictures of big, green fields seem to end up either brown or dark blue.
• The color weighting may be off to some degree.
• I will either try to make it more accurate or just let the user adjust it themselves.
• It could also be the palettes' limited color selection.
