Living with red-green color blindness: practical everyday tips

Red-green color vision deficiency affects roughly 1 in 12 men and 1 in 200 women. It's rarely a big problem, but it adds friction to small daily tasks - is this meat cooked, do these clothes match, which wire is which? Here are practical strategies, and where a phone or laptop can quietly help.

In the kitchen

• Don't judge doneness by color alone. Use a meat thermometer and times rather than "is it still pink?" - the pink/brown transition is exactly the kind of red-green cue that's hard to read.
• Ripeness is tricky. Lean on firmness and smell. For bananas, texture and spots; for tomatoes, give rather than redness.

Clothes and matching

Matching outfits is one of the most common frustrations. Two tactics help:

1. Name your wardrobe once. Identify a color and save it with your own label ("navy blazer", "olive chinos") so you're matching names, not guessing hues. Satura's Identify tool names any color from your camera and lets you save it to a library.
2. Check pairs before you commit. The match-or-clash tool tells you whether two colors actually go together - and whether they'd still be distinguishable to others with CVD.

Screens, charts and maps

• Ask for labels, patterns or icons, not color-only legends. A red/green status dot is far clearer with a ✓/✗ or a shape.
• When a chart is color-only, run a screenshot through Satura's correction filter to separate the confusable colors, or the simulator to confirm what's actually ambiguous.

At work

• For wiring, components, or anything safety-related, confirm with a colleague or a labelled reference - don't rely on color memory.
• If you build software or design, test your palettes for CVD-safety. The contrast checker and match tool make this a few-second job.

Tell people - it helps

Most people have no idea what color blindness looks like. Satura's "show a friend what I see" puts a normal and a CVD view side by side with a share button, which is often the fastest way to explain it.

A quick check

If you've never had it confirmed, the free color blindness screening runs privately on your device and gives an instant result. It's a screening aid, not a diagnosis - but it's a useful starting point, and it's free.
