The color of UAM and COB forecast lines are too similar #918

Description

Is your feature request related to a problem? Please describe.

The colors used for the UAM and COB forecast lines are too similar and often difficult to distinguish between. They also do not match the colors of the lines used in Nightscout which leads to confusion.

While these colors have been used since FreeAPS X, they differ from the standard colors displayed in Nightscout (and AndroidAPS). This makes switching between Trio charts and Nightscout charts not as intuitive.

Describe the solution you'd like

I think the best option would just be to adopt the NS/AAPS colors, but just changing the UAM line to a different color would be sufficient.

. light dark
Trio
NS/AAPS

Describe alternatives you've considered

Since COB is the only forecast line that uses a standard (dynamic) color instead of a singe custom color.... turning on "Increase Contrast" in Accessibility settings for Trio makes all orange in the app (including the COB line) appear redder. While helpful to make the lines easier to distinguish, it'd be nice to not have to change the appearance of standard colors used throughout the app, and I'd rather have COB stay orange and make UAM red.

Additional context

Images would have to be updated in Triodocs, and colors should be updated in LoopFollow.

Technical Details

The color used for the IOB line is Color.insulin, which is also used throughout the app for other colors. So maybe consider keeping the current shade of blue used for this line.

Color.orange is used for the COB line as well as for other carb related items in the app. So maybe consider switching the color for all of these elements to a newly created Color.cob or Color.carbs, similar to how Color.insulin is used.

User Impact

Semi-frequent user posts pointing out their difficulty to distinguish between the UAM and COB line. Also semi-frequent user posts confused about why their app looks different than others' because they didn't realize they had Increase Contrast turned on.
