Open →Color Mixer
Digital RGB reference only. Physical paint mixing depends on actual pigments, concentration and surface.
Value Checker
Choose a color to calculate luminance and compare it with a clickable value scale. The scale is a value reference, not a fixed palette.
Value scale — click any swatch to compare a neutral at that value.
Grid Maker
Use the density preview to choose a workable reference grid before drawing.
Brush Library
Choose a shape to see a typical use profile. Manufacturer dimensions and fibres still belong in the verified Brush database.
Versatile shape for lines, washes and controlled points depending on size and fibre.
Palette Planner
Choose up to five reference colors. This plans visual roles, not pigment chemistry.
Paper Weight Reference
Traditional “lb” paper weights are not a universal unit conversion because basis sheet sizes differ. Use this as a Watercolor reference table, not a mathematical equivalence.
| Common watercolor reference | Approx. gsm |
|---|---|
| 90 lb | ~190 gsm |
| 140 lb | ~300 gsm |
| 260 lb | ~560 gsm |
| 300 lb | ~640 gsm |
