Red carries the hex code #FF0000, which resolves to rgb(255, 0, 0) and hsl(0, 100%, 50%): the red channel at maximum with green and blue at zero. That purity makes it the loudest color available in sRGB and the hardest one to place responsibly in an interface. Full-strength red...
Gray’s HEX code is #808080. All three RGB channels sit at exactly 128 — half strength, zero hue, 50% lightness — making gray the only color in this series with no color in it at all. That achromatic status is precisely why gray does more work in interfaces than any...
Cream’s HEX code is #FFFDD0. Red and green run at or near maximum while blue drops to 208 — hue 57, full saturation, 91% lightness — which makes cream exactly what color theory says it is: the pastel of yellow, the way pink is the pastel of red. That whisper of warmth...
Dark blue’s HEX code is #00008B. Only the blue channel is active, at 139 of 255 — hue 240, full saturation, 27% lightness — placing it a precise step above navy on the same pure-blue axis. It’s the color of authority with a pulse: deep enough for institutional...
White’s HEX code is #FFFFFF. All three RGB channels run at their maximum of 255 — full red, full green, full blue — producing the brightest value a screen can emit. White is achromatic: zero hue, zero saturation, pure lightness, and it holds a distinction no other...
Brown’s HEX code is #964B00. Under the hood it’s hsl(30, 100%, 29%) — which reveals the secret most designers never learn: brown is simply dark orange. Full saturation at hue 30, compressed to 29% lightness, produces the earthy warmth that coffee brands, craft...
Yellow’s HEX code is #FFFF00. Red and green both run at maximum while blue sits at zero — hue 60, full saturation, 50% lightness — making it the brightest-feeling color a screen can produce. It also holds two records in this series at once: the best contrast ratio...
Emerald green’s HEX code is #50C878. It sits at hue 140 — green with a deliberate lean toward blue — at 52% saturation and 55% lightness, the recipe that gives it the jewel-toned brightness the gemstone is named for. Luxury brands, fintech products, and premium...
Rose red’s HEX code is #C21E56. It sits at hue 340 — the corridor between red and magenta — with 73% saturation and 44% lightness, giving it red’s energy with a cooler, more romantic cast. Beauty brands, lifestyle products, and any interface that wants passion...
Blue’s HEX code is #0000FF. The blue channel runs at maximum while red and green sit at zero — hue 240, full saturation, 50% lightness — making it the purest blue a screen can physically display. It’s also the most used hue in interface design, anchoring the...
