ELI5: Why does color affect heat absorption?
gpt
It's not color that affect heat absorption. It's the physical propriety of material that absorb different wavelenght of light. So if a material absord all visible wavelength of light it will appear black because it doesn't reflect back light into our eyes. 

Alternatively, something white is made of something that reflect all the visible light back so we see the color white. 

Something that absorb more wavelength will absorb more energy from that light, which will become heat.
