As for me me you are right Ceg, I aim when buying bulbs for what makes me feel good when viewing my aquarium and these are the bulbs with the least yellow visible but not as cold as when using let's say 8000k tubes so that the red plants still look red. So, a combination of high reds and blues (pinky + 9000k+) was the best choice to achieve this after trying dozens of combinations.
