Red ink does reduce the brightness of a white page. That is how it works. It absorbs the part of visible light that is not red and reflects the red part of the light. That is necessarily less bright, although perceived brightness is more complicated than just total light.

For a reflective display, a red filter lets red light pass in both directions and absorbs non-red light.

If you have green text on a white background, the capsule(s) behind the green filter would show white for each "color pixel" that is part of a letter. The capsule(s) behind the red and blue filters for the same "color pixel" would have to show full black. The capsule(s) behind the clear filter for the same "color pixel" could be anywhere between full white and full black depending on the compromise between unsaturated and dark you are will to make. So you only have one fourth as many pixels for drawing one color text as you would have on a monochrome display. You could play some tricks around the edges of the letter using blue and red, but it probably not look good on a reflective display.
