So
@OF, how have you adjusted?
I'm not exactly sure what the questions is. If it's 'how can you use the heat levels on Air?', fortunately I can count that high. I go to the bottom (or top) and count up or down to the step I want. I started using step 3 by default, now I use step 2. Color not withstanding. I can see blue just fine, and white usually since it's 'blue and other colors' but not enough of the other 3 to depend on. Some are worse off than I am.
If it's 'how have you adjusted to being color blind?' as a general question, there is none since you're that way from birth, there is no 'adjustment' per se. Up until I was 14 or 15 and went to the eye doctor for headaches due to eye strain reading (far sighted) and was tested in due course I wasn't identified as being color blind, I was simply judged stupid by the school system in Kindergarten when I was discovered using the wrong crayons. "Has trouble with colors" was passed along with the other key information.
I think it's generally ignored by those not involved. Not everywhere, for instance the funny color of green traffic lights is because of us, to make it different from red. And the position of the 3 colors is fixed for that reason as well. Strangely, at night, I can't tell flashing yellow from flashing red at the distance. I have to get close enough to see the frame of the lights to tell. I have to treat them as flashing red until then which means I approach slower than most......so there I've adjusted by being sure the guy behind me stays sharp and doesn't rear end me I guess?
Color changing LEDs area seductive idea, I think. Engineers love how it makes it simpler to build, the Suits (sales types) love the bling. If the few involved in such choices don't consider it, they don't consider it.
As a fun aside, Herbal Aire used to use a tiny version of those horrid red/green LEDs as it's only display, it had four red LEDs shining down for bling. You needed to see the color change to know when it was at correct temperature. The next (current) version, H2.2, replaced the four LEDs with a large 3 color one that uses the 'sea green' like traffic lights (very vivid) shining down under the uint tied into the temperature/heating display. Wanna guess why? After 'splaining the issue to them (they hadn't considered it, of course, not being color blind personally) and suggesting the next version use part of the light show to give us a clue they went the extra mile IMO.
