Chrovis is the fastest way to explore color theory on iPhone. Pick any color, instantly see every classic harmony scheme — complementary, analogous, triadic, split-complementary, tetradic — as clean, copyable swatches. No account. No network. No friction.
Pick a color by typing a HEX value, dragging HSL sliders, or opening the system color wheel. Tap any swatch to copy HEX, RGB, or HSL in one tap. The Format Converter lets you type any format and see all three live.
Designed for designers, developers, and artists who need a quick, reliable color reference that works everywhere — even offline.
