perf: Cache normalisedColors output (#57896)

Summary:
While looking into something I saw this processColor function , for every color we  are calculating normalise Color even though it would have been done earlier.
This is a simple approach. Maybe we can add things like LRU. With some simple scripts(Rendering around 1000 cells) I found around 13% faster .
