I can turn on all three of the LEDs to amplify the brightness and create a composite RGB colour?
Yes, absolutely! There are 3 discrete LEDs so the colour mixing isn't perfect, but you will get more brightness. I'd also make sure you get up to date firmware as we found a way to boost the LED brightness.
The LEDs are quite bright, but in direct sunlight you might have to peer at it a bit with the white case.
There is a dark cover (which I think you ordered?) which will improve matters quite a lot in bright sunlight so I'd definitely give that a try. I tried it here under a bright spotlight and the light was very obvious.
