That really depends on what you think of as "red". I tend to categorize automatically into "scarlet" and "crimson" (too many hours spent with oil paints and pastels over too many decades), rarely ever seeing anything as "merely red", and that division is sometimes blurred by monitor calibration (or, rather, the lack of same). It's not so much that I see different things than other people with good colour vision, just that I have learned to do a primary categorization of "red" with two buckets instead of one.
