Colored solar panels that mimic tiles roof hit 95% efficiency compared to regular solar tiles
(interestingengineering.com)
It's 95% of regular panels, so it's 5% worse.
I would go with regular panels in that case, unless they are shaped like tiles and can provide better coverage of the roof. 5% efficiency drop but 15% coverage increase could be worth it. But I expect install costs would be quite a bit higher
