Q: Are these light and breathable enough to use under a cycling helmet with it being assumed right now?

Not sure I understand the last part of the question but they are light enough to wear under a cycling helmet. They are made of light, solid stretch fabric, and not a mesh fabric like other brands.

Q: Why does every color combination have to have a black one? If you want your head cool in summer (even under a bike helmet) who wants black?

Multiple customers , the idea is to sell items is to give people what they want. Supply and demand the colors are bought in a package. There is no where you can change the choice of the three pack. If you don't like what's there you don't have to buy it.
