Hi Jordi,
i love color discussions, everyone got something to say!
And that's true. We all see different colors for the same situation. And you can make the test, try to see if your eyes have the same rendition. (one eye at the time).
That thing about women seeing more colors than men is also 'a bit' true (there more women with better color recognition than men, don't know the percentage)
Men have also better night vision, is also 'a bit' true.
I don't know if there is the 'best color' lamp for aquarium, maybe the...
I reached that point when the best color is the one that fit's me.
Our brain auto calibrates the white balance very quickly, that's why we normally miss the color changes.
But if we have then side by side is more easy to compare, or if we move fast from different light color places.
There are some colors that activate 'low level' emotions, the ones who work in publicity knows that (for sure)!
The warm tones, of the fire, in center of the house is something that makes a living room cozy.
The tank's have the blue tone of water, the green's of plants and sometimes the red's. It can be the red's of the plants or fish's but maybe also a bit of the 'emotional fireplace' that we lost somewhere...
The best color for you is the one that pleases you more.
Maybe you can add more lamps and change the color for your mod!
color is one of those things...
cheers
