Welcome to the Pintado Art Tools Hub. We built these utilities specifically for hobbyist painters, atelier students, watercolorists, and digital illustrators who want accurate preparation aids without paying for bulky subscription software or handing their photos over to unknown cloud servers. Every tool below runs 100% locally in your web browser via HTML5 Canvas and Web APIs. This means your personal portraits and artwork references stay private on your machine, calculations execute instantly with zero network latency, and the entire suite remains completely free to use.
Mix two or more paint colors using paint-realistic subtractive (RYB) color physics. Avoid additive RGB monitor distortion, preview resulting pigment names, and extract 6-color palettes from uploaded photos.
Convert portraits, landscapes, or pet photos into clean, high-contrast line art outlines. Features adjustable line thickness, noise suppression, and print-ready formatting for coloring books or tracing.
Overlay uniform square cells or custom column/row grids onto any reference photo. Includes atelier diagonal sight-size lines, coordinate markers (A-Z, 1-N), and downloadable reference sheets.
Simplify reference photos into 2-value Notan, 3-value tonal masses, or 5-step posterized value studies. Review live value distribution meters to balance light and shadow before applying paint.
Overlay the Fibonacci Golden Spiral, Rule of Thirds, 14-line Dynamic Symmetry Baroque armatures, and Golden Triangles. Rotate and flip guides to align with your focal subjects.
Match your reference photo to standard canvas dimensions (8×10, 11×14, 16×20, 18×24, 24×36 in, or ISO A4–A1). Check exact crop bounds, image loss percentage, and scale factors.
Explore complementary, split-complementary, triadic, and analogous harmonies on a traditional 12-hue subtractive RYB artist wheel. Read tube pigment recipes and generate tint/shade scales.
A museum-quality painting is not made by guesswork—it is built through methodical, disciplined stages. Here is how professional artists connect Pintado’s 7 tools from reference selection to final glaze:
Upload your reference to the Canvas Aspect Ratio Scaler. Determine which standard canvas size (e.g. 16×20 vs 18×24) fits your subject with minimal cropping, avoiding awkward edges.
Run your image through the Golden Ratio Composition Tool. Align the Fibonacci Spiral and Dynamic Symmetry lines with key focal eyes, horizon breaks, and gestures.
Test your composition in the Value Study & Notan Converter. Check that the 2-value graphic reads clearly across the room and block in your 3-value underpainting with confidence.
Use the Grid Method Calculator or Photo to Coloring Page Converter to transfer exact contours onto your canvas using light graphite or carbon paper.
Consult the Artist Color Wheel for harmonious triadic or split-complementary pairings, then simulate realistic subtractive blends in the Color Mixer & Palette Generator.
