Checking your own graphic for colour-vision deficiency with colorspacious, from its documentation

Coverage

For designers who want to see how a poster, chart or title card might read for people with red-green or blue-yellow colour-vision deficiency. It sets out what the colorspacious documentation says about the simulation and adds an untested checklist for applying it to a graphic. The documentation never mentions posters, so that step is the curator's inference, and nothing was installed or run.

Useful starting points

• Colorspacious warns that the simulation conversion goes from the special colour-blindness space to standard sRGB, which is the opposite of what most people expect.
• The documentation says severity runs from 0 for regular vision to 100 for complete dichromacy, and that for the rarest type probably only 100 matches real people.
• If an element can only be read by its colour, consider adding a label or pattern. This is the note's own suggestion, not a statement in the documentation.
