Designer
UI / Brand / Visual
"I need the exact blue from that website for my Figma mockup. And the client wants the brand guide in HEX."
Developer
Frontend / CSS
"I need to match this color from the design comp. HSL makes it easy to adjust lightness. HWB for CSS4."
Pre-press / Packaging
"The brand color is on their website but I need CMYK values for the printer. No one else gives me CMYK."
Anyone
Curious / Learning
"What color is that? I just want to know. Pick it, see it, maybe save it for later."
