See image 1 - We see the band colour in workouts for the current exercise (circled), great. Would be good to have the same symbol in the 'Previous' bit of this screen.
See image 2 (exercise history) - Would be good to also have the band colour here, and anywhere else where the band is mentioned, instead of just "assist.(5)".
I reckon most people link the colour of the band to the assistance/resistance rating more so than the number system used.
