Colour Blind
A screenshot the way a colour-blind player sees it, with the colours that end up looking the same.
You want to check that your UI or map colours still read apart for colour-blind players.

Load a screenshot and pick a type: protan, deutan or tritan at any severity (the Machado 2009 model, in linear RGB), or no colour at all. It shows the result next to the original, or on its own.
It finds the main colours and lists the pairs that end up looking the same, with swatches, and boxes where they are on the simulated side. Click a spot to see its colour before and after, and what it gets mixed up with.
