Change "mild" symptom color to yellow or orange to offset from "none"
At the moment there is only a slight color variation between NO and MILD symptoms. When I show my calendar to therapist/doctor they interpret all these greens as “good days (= no symptoms)” which is frustrating and doesn’t mirror my reality. I would love for mild symptoms to be visually different in their color representation because it would more easily and clearly showcase the intensity and occurrences. A yellow or orange tone would be fitting.
