You can do both with this function. Light always has a "color"; If you want white light (the default), set r=b=g, e.g. to 255 for maximum brightness.

It's doesn't whiter than white, so you can't increase the intensity above 255,255,255. You can you lower values...it's just like in any paint program if you are picking some color.

Thanks above everyone, i now know it,rgb not only means the color but also means the strength of light.Strong light or weak light all belong to RGB.

In case you still wonder why your lights and textures are kinda dark:
You probably have, as all people, set your device to automatic brightness. This is rather dark for games.

You can try this snippet:

WindowManager.LayoutParams lp = getWindow().getAttributes();
lp.screenBrightness = 1.0; // or whatever
getWindow().setAttributes(lp);

to override brightness settings.

Not all devices or users will like that, but it may be worth a try. In Armada, I set the brightness to 0.85 per default, but the user can deactivate the override.
