Will painting a swimmimg pool a dark color promote algae to grow more than a light colored painted pool? Answered

I am picking a new color for my inground swimming pool with filter no heater. Wanted to change to color from a basic light blue to a more modern darker color.  Was told dark colors allow algae to grow more than light colors.  Any truth to that statement?  Also because the pool is not heated which color would help keep the water warm?  I am guessing that a dark bottom pool would be warmer than a light bottom pool.

I agree with iceng, light will help the algae to grow not the surface colour. I would also guess as you have, a darker colour could possibly allow the water to warm up more than a lighter one.

Light feeds algae. Dark paint hides it from view, until it gets really established.
