Does age affect the chickens leg color?

My 2 RIR hens who are 3 years old used to have vibrant yellow legs. Now they are barely yellow and they are more tan. Is this just due to their age? They don’t act much differently then they used to other then just age changes and less eggs.

Age, environment, and point in the laying cycle can affect leg color. If they are otherwise normal, there is no problem.
