About Chromaforge
A precision colour studio for designers who care about how their work looks once it leaves the screen.
What it does
Type a HEX value, get accurate RGB and CMYK readings, plus a side-by-side preview of how that colour will reproduce on three different output paths — a calibrated monitor, a professional offset press (FOGRA39 coated), and a consumer colour laser printer.
Beyond the swatch, Chromaforge generates six classic harmony palettes (complementary, split-complementary, analogous, triadic, tetradic/square and double-complementary), suggests five CMYK-safe neighbour colours, and lets you push the active colour through tint, shade, tone, saturation, hue and brightness sliders with live print soft-proofing.
Why it exists
Most colour tools online stop at the screen. As a print designer, the question that actually matters is: will this still look right on paper? Bright sRGB colours often clip badly in CMYK, pastels mush together on consumer toner, and shadows pick up unwanted warm casts. Chromaforge surfaces those shifts before you commit to the press cheque.
Under the hood
All calculations run in your browser. Your colours never leave your device.
Who built it
Chromaforge is an independent project by a small team of designers and engineers who wanted a colour reference they could actually trust before sending artwork to print. Feedback, bug reports and palette requests are welcome at hello@freecmyk.com.
