Painter's Toolkit

21 tools for painters, fully offline: match any color to real pigments, mix them with true spectral physics, study values, and transfer your drawing to canvas.

Painter's Toolkit is a complete digital workshop for painters: 21 tools that fit in your pocket and work entirely offline.

Point it at a reference photo and it tells you which paints to mix. Study your values, plan your composition, transfer your drawing, and check your work — all in one place, no internet needed.

COLOR • Color Picker — tap any pixel in your reference and match it against real pigments, ranked by perceptual difference • Paint Mixer — genuine Kubelka-Munk spectral mixing, so yellow and blue actually make green instead of mud. Two-point undertone model reproduces how a paint behaves pure and thinned out. • Mix Suggestion — give it a target color and it searches your pigments for the combination that gets there • Color Wheel & Harmony — six harmony types; send any result straight to the mixer • Your own pigment library — add paints by hex code, from your photo library, or by photographing a manufacturer swatch card • Limited Palette — repaint any photo using only the colors you actually own • White Balance and color blindness simulation

VALUE & COMPOSITION • Value Analysis — grayscale with 2, 3, 5 or 9 tone steps • Simplify — squint blur that reveals the big shapes • Outline — edge detection with adjustable line weight, invertible for a chalkboard look • Warm/Cool Balance — a pixel-level temperature breakdown of your reference

DRAWING AIDS • Grid — thirds, golden ratio, diagonals or custom rows and columns, with pinch to zoom • Perspective Correction — mark four corners and get a flat rectangle back • Vanishing Point — one, two or three point guide overlays • Proportion — sight-size measuring with a unit bar • AR Reference — see your reference on the canvas through the camera • Mirror, Compare, sketch layer and a practice timer

WORKSHOP • Projects and a reference library, linked to your palettes • Browse public domain artworks from The Metropolitan Museum of Art and the Cleveland Museum of Art • Chain tools together: the output of one becomes the input of the next

PRIVACY Everything runs on your device. No account, no analytics, no tracking. Your photos, projects and palettes never leave your phone. The only network requests are the optional museum archive browsing.
