Operational camouflage and Royal Navy aircraft colours

Why did the Royal Navy abandon blue-and-white aircraft and yellow-and-blue helicopter schemes?

Operational visibility requirements explain the broad change; joint F-35B arrangements are a further consideration for distinctive naval markings.

Older blue-and-white aircraft and yellow-and-blue helicopter schemes are contrasted with colours intended for current operations. Reduced visibility is the reason offered for the change. The jointly operated F-35B force also complicates the idea of a wholly separate naval appearance. The answer does not trace the introduction date of each paint scheme.
