 On the face of it, this view of Reid seems counter-intuitive. Many of “those men not tutored by modern philosophy”, have a lot to say about colors, and would be surprised to be told that colors are unknown qualities. Red, for example, is the color used by many revolutionary parties, good for annoying bulls, my favorite color, the color of my true love’s lips, and so on. We can give paradigms of blue, red, yellow, turquoise, mauve, etc. We often say things such as “that is a better blue than this”. One suspects that they (the untutored) would be puzzled by the remark that red is some unknown quality (for more on this, see Hacker 1987: 186).
