Red Plus Purple Swatch Test: What Real Pigments Actually Create
By James H. Sterling
Q1: Is red and purple considered a warm or cool color?
A1: It functions as a bridge color. A red-heavy mix (like raspberry) reads as predominantly warm, while a purple-heavy mix (like plum) reads as cool. Its temperature depends entirely on which parent pigment dominates the ratio.
Q2: Can you make true magenta by mixing red and purple?
A2: You can achieve a shade resembling magenta, but you cannot mix pure process magenta from traditional red and purple paint. In color printing (CMYK), magenta is a primary pigment. Mixing red and purple subtracts light, so the result will always be slightly darker and less saturated than pure printer magenta.
Q3: Why did my red and purple paint turn brown?
A3: Your red paint likely contained yellow undertones (such as Cadmium Red). Combining yellow, red, and blue creates tertiary brown. Swap to a blue-biased red, such as Quinacridone or Alizarin Crimson, to keep the mix clean.
Q4: What is the formal name for red mixed with purple?
A4: In formal color theory, the resulting tertiary hue is called red-violet or red-purple. Popular cultural names include burgundy, plum, maroon, mulberry, and wine, depending on brightness and black value.
