Wherever there are blinking animations (style customiser colour animations, colour indirect tag bindings, etc.), these should all be synchronised rather than running off their own independent timers. When multiple components on a screen are blinking and they're all blinking with different offsets, it looks horrible and unprofessional.

The alternative is to use the expression language in combination with an internal clock tag, however this is a non-visual method making it difficult to see what colours you've selected.
