Mixing yellow and green FAQ

Mixed as paint, yellow and green make a green (#5CB72F). As light on a screen, they make a light yellow (#FDF445), and blended in CSS with OKLCH they give a yellow (#94B328).

Light adds up instead of absorbing, so yellow and green light make a light yellow (#FDF445). 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 yellow to one part green gives a green (#84C626), while one part yellow to three parts green gives a green (#3CA536). To lighten the result add white, and to darken it add a little black.

Use color-mix(in oklch, #FCD200 50%, #1E8C45 50%), which gives #94B328. OKLCH keeps the middle of the mix bright, while mixing in sRGB tends to turn it gray.
