controlActivated

These colors were present in Android framework before Android U, and used by MDC controls. They should be avoided, if possible. It's unclear if they're used on multiple backgrounds, and if they are, they can't be adjusted for contrast.* For now, they will be set with no background, and those won't adjust for contrast, avoiding issues.

colorControlActivated documented as colorAccent in M3 & GM3. colorAccent documented as colorSecondary in M3 and colorPrimary in GM3. Android used Material's Container as Primary/Secondary/Tertiary at launch. Therefore, this is a duplicated version of Primary Container.

For example, if the same color is on a white background and black background, there's no way to increase contrast with either without losing contrast with the other.
