answer:Depends what colour it is….. That is what colour is. The electromagnetic spectrum is broad. Some waves are many times the size of buildings, others are tinier than atoms. A small portion of it, the visible region, is what we thing of as light. Different colours are represented by different frequencies, or wavelengths, A piece of acrylic (or anything for that matter) will reflect, absorb, or transmit different frequencies, to different degrees, all the way along. Acrylic is likely to transmit most of the spectrum (X-rays, microwaves, gamma waves &c), absorb some of the infra-red, and reflect/absorb different parts of the UV/Vis region, depending on its colour. Using chemistry to cause it to reflect/absorb different wavelengths (frequencies) of the visible region is how the colour is created
