Viridian turns any photo into a paint-mixing plan you can follow at the easel. Touch a color in your reference and Viridian names the pigments to reach it, in mixing order, from the paints on your shelf: start with Yellow Ochre, add Ultramarine Blue, mute it with a touch of Burnt Umber. You get the recipe, not a hex code. Paint in oil, acrylic, gouache, or watercolor. Switch your medium and every recipe shifts to match how that paint handles. SAMPLE ANY IMAGE - Load a photo, capture a scene, or paste an image link - Pinch to zoom, drag to sample, with a loupe for pixel-level precision - Flip any reference to black and white to read its values before you commit to a color MIX WITH REAL PAINT - Recipes drawn from 24 studio pigments, from Titanium White to Burnt Umber - Tell Viridian what you own; it mixes from your shelf and substitutes when a tube is missing - Honest confidence and adjustment notes instead of false precision SEE THE MASSES WITH BLOCK-IN MAP - Turn a reference into flat shapes of value, the way you block in a painting - Six levels, from a 2-value notan to a 12-value study - Hold the map to compare it against the photo - Every shape carries the mix that fills it BUILD PALETTES WITH INTENT - Generate palettes of 3 to 10 colors from any color you save - Seven schemes: complementary, analogous, triadic, split complementary, tonal, muted earth, high contrast - Each swatch labeled by its job: shadow, midtone, highlight, accent, background - Lock the colors you love and regenerate the rest LEARN THE CRAFT - Twelve painting techniques, from glazing to sgraffito, each cited to a standard reference - Filtered to the medium you paint in KEEP IT ALL TOGETHER - Save colors with their recipe, notes, and the image they came from - Sample straight from your saved inspiration screenshots - Search and filter your library by color family or source Everything runs on your device. No account, no tracking, no network. Paint behaves differently by brand, opacity, medium, surface, and light. Treat every recipe as a starting point for your palette knife, not a promise.
