ToneDeltaPair

@RestrictTo(value = LIBRARY_GROUP)
class ToneDeltaPair

Documents a constraint between two DynamicColors, in which their tones must have a certain distance from each other.

Prefer a DynamicColor with a background, this is for special cases when designers want tonal distance, literally contrast, between two colors that don't have a background / foreground relationship or a contrast guarantee.
