[Feature request] Colour-blind-friendly colourway

[onchov]

Hi, thanks for the great app that Breathly is!

I returned to it after a while and I noticed the looks changed completely from what I knew.

My vision is impaired and the light theme isn't easy on my eyes -- I'm not sure if it's the 'rosette' shape rather than the old circle, or the colours, or the combination of both. Switching to the dark theme makes everything more legible for me, but then again, I'm not a fan of dark themes in general.

If possible at all, I would request an optional colourway that's friendly to people with not so great eyesight. (If you google for something like color-blind+interface+guidelines, you should find some useful info about how an interface can be problematic and how to address that). (FWIW, the old light-blue circle on the blue background, if I remember the colours correctly, worked perfectly fine).

Many thanks.
