Red and yellow, of course. The light you see is being transmitted and not absorbed.

To do this, it would have to be black, which is the lack of color.
why does plants color change to black when absorbed all wavelengths

The light with the longest wavelength, which is still visible for us, is red light.
Red and yellow
Different materials absorb different wavelengths of visible radiation from sources like the sun or light bulbs. The wavelengths that are not absorbed are reflected as visible radiation, and the color we see depends on the wavelength of that reflected light, with a longer wavelength correlating to more reddish colors, and shorter wavelengths with more bluish colors. White objects reflect all of the visible radiation that strike them, which is why they absorb less heat than black objects, which reflect much less visible radiation.

Most of the visible light spectrum except green wavelengths is absorbed by the chlorophyll molecule and is usable in photosynthesis as a source of energy for plants.

Carotenoids have conjugated bonds. Wavelengths of visible light are absorbed when electrons are excited to higher energy levels. The complementary colour is to that absorbed is observed.
Most of the longest wavelengths (reds) of visible light are being reflected, compared to the other colors. The shorter wavelengths are mostly being absorbed.
Red or blue light are the wavelengths of the visible light spectrum that are most absorbed by plants.
