Show HN: Find matching acrylic paints for any HEX color

A scrappy Show HN tool just promised to translate any HEX (a web color code) into real acrylic paint picks—and the crowd immediately split into praise vs. physics. Hobbyists cheered that it covers common craft-store brands and even named web “CSS colors.” One grateful painter admitted they usually buy a handful of near-matches and hope for the best, and this could finally spare their wallet.

Then the color cops arrived. One skeptic crashed the party with a mood-killing reminder: lighting and surroundings change how paint looks, so your perfect on-screen match can turn into a surprise on the wall. Another waved the nerd flag, warning that matching screen light (RGB) to real pigments (subtractive color like print inks, see CMYK) is “perilous.” Meanwhile, miniature painters started chanting: add Citadel and Vallejo! The wishlist frenzy exposed a deeper tension: is this a handy shopper’s compass—or a science fair project doomed by physics?

The plot twist: transparency. Curious devs demanded receipts. Did the maker scan real swatches, scrape product photos, or just map color names? Depending on the method, accuracy swings wildly. Cue memes about “my monitor lied to me,” the eternal Lighting Gang vs. Math Gang, and a chorus of practical users saying: even if it’s not perfect, it’s way better than guessing in the aisle.
