Yeah, don't worry too much about other colors. Just know that you should have your blues up higher than your whites, 20-30% higher than your whites I'd say. Maybe higher. So set your whites to 40% and your blues between 60-70%. If this leads to algae growth you can always dial back both spectrums. Definitely do not add a cleanup crew first, unless it's a very small number of invertebrates and their is sufficient algae growth to support them. Or unless you plan to feed them algae pellets or something else like that. Most of the time, people add fish first and wait several months for the tank to stabilize and mature and get algae growth before adding a cleanup crew. Something to think about.
