Mixing red and brown FAQ

Mixed as paint, red and brown make a red (#9E2A35). As light on a screen, they make a red (#EC4F4C), and blended in CSS with OKLCH they give an orange (#A83D21).

Light adds up instead of absorbing, so red and brown light make a red (#EC4F4C). That is why screens can show bright yellows from red and green light, while the same paints would turn brown.

Change the ratio. Three parts red to one part brown gives a red (#B3233A), while one part red to three parts brown gives a brown (#8D3330). To lighten the result add white, and to darken it add a little black.

Use color-mix(in oklch, #D1193E 50%, #7B4A2A 50%), which gives #A83D21. OKLCH keeps the middle of the mix bright, while mixing in sRGB tends to turn it gray.
