Incoming light spectra are convolved with the frequency responses of the eye's photoreceptor cells (basically R, B, and G for color). The Sun, and your computer screen, achieve white using quite different spectra. They just have to poke the cells to similar extents. Forgetting that the eye matters is common. "Spectra peak in green, so Sun is green" is one (not so common) resulting misconception.
