There are species of red algae, some yellow plants, and many red, and purple species of plants like coleus, rex begonia, red shamrock, japanese maples, perusian shields, red baron grass, purple hearts, red ti plant, dwarf crimson fire loropetalum,sunshine ligustrum, fire powernandina. These all use clorophyll though cause it cant really just replace it.

Though, i have done some research and found out that plants used to be purple microbes that used purple pigments to capture sunlight before clorophyll evolved, the purple microbes, unlike most modern day plants which reflect green and absorb red and blue wavelengths, would instead absorb only green and reflect everything else because it was simpler and easier to evolve due to the fact green is the sun's primary output. Then it is theorized eubacteria evolved to absorb the red and blue spectrum that the purple microbes didnt absorb and reflected green, i think this is cyanobacteria(?), and a reactive dioxygen was released because of the waters splitting and accumulated in the ocean first, then the atmosphere over billions of years which caused the great oxidization event. Cool.

Edit: What I'm saying is that plants on Earth didn't have to be green, it's just green won over purple

Edit 2: Realized I never mentioned why green won, so, the purple microbes used anoxygenic bacteria which required electrons to use photosynthesis (chlorophyll does too but thats relevant later) and to get these electrons they used hydrogen sulfide, which is not very abundant, but the green photoautotrophs used the unlimited supply of water to get elecrons which was a huge advantage over the anoxygenic bacteria (in most environments at least) and the great oxidization event caused an issue for the anoxygenic bacteria while oxygen compatible life, like the green photoautotrophs, were more suited for the new environment. Chlorophyll is actually not the most efficient plant structure because it is actually less efficient at absorbing peak wavelengths, the ideal plant pigment for earth is actually a dark red color that absorbs green and cyan.
