I was aware of this when I first designed it, and that’s why there are three different visual indicators if you’ re hitting your targets.
- Red/Green bar color (doesn’t work for color blind people)
- Intensity bar matching target line
- Current power and target power metrics
Let’s say we just had a dot that would change colors (green to red) without #2 and #3. That wouldn’t work. But since we are encoding the information with both #2 and #3 we’re good.
This is like US street lights. If they were just one light there would be lots of accidents. But because it’s encoded by position too (top red, bottom green) it works just fine for color blind people.
