Summary: The hex8 specified version is #rrggbbaa so it would be great to have the internal representation be 0xrrggbbaa to prevent confusion. This pull request changes the internals of normalizeColor. It changes a lot of lines but there isn't any big changes. Small changes: - Use | instead of + for number operations - Use x << 24 instead of x * (1 << 24) - Have hslToRgb return pre shifted number processColor is still sending colors the 0xaarrggbb format to native and tests still pass without changes.
