Sometimes the straw is a slightly different shade. So does not 100% match as the same colour.  Personally I think it still looks great 😊 🌈 Lids can look a shade different also, but again I feel it doesn’t detract from the cup! (Currently the red lid is a sl. Brick red lid). 
The current red does have a few specks in the surface (see pic). 
It’s difficult to get totally accurate colours in pictures. I’d say the multi cup pictures in rows, rather than a circle is the best colour match looking.
