@thibaultmol I work in a corporate environment, where PowerPoint is everything.

I never realized that coding figures etc in red (for negative) and green (for positive) wasn’t accessible for people with red/green blindness, until I worked with a red/green blind manager.

Solved this by supplementing the colors with symbols like plus/minus.

@slothrop @thibaultmol I made all my visuals in blue-yellow for a while until I found out that there are more forms of colour-blindness than just red-green. Nowadays if it's something important and intended for a wide audience, I run it through online colour-blindness checking tools.
