I just wondered why animals and plants in (sub)tropical regions are so much more colorful than in colder aeras of the world. Here in Europe the main colors are grey, brown, black, maybe green. Why is that?

It's not camouflage, it's sexual selection. The stressful conditions of colder climates make organisms (plants and animals) invest their energy and time in survival and maintenance. In the more comfortable tropics, organisms can invest more in elaborate courtship displays. Tropical areas have much higher plant and insect diversity, which means more specialization through coevolution.

It is a camouflage garb that nature has equipped them with as a protection against the many predators which inhabit the jungles of these regions. In a jungle warfare, soldiers wear camouflage uniforms to protect them against the adversary. It is a technique copied from nature.

They are brighter so they can blend in with the surroundings, as it contains a lot of bright fruit and plants with outstanding colours.
