Color
These examples cover palettes, colormaps, and color driven by a value or by time.
| Example | What it shows |
|---|---|
| Colormaps | the eight perceptual Colormap ramps drawn as horizontal bands that map a value to a color, with the seven cosine-gradient CosinePalette presets scrolling in a labeled section below |
| ColorVision | a photograph of woven blankets and two palettes shown four ways, with a bar that marks every pair of colors that merge, and Filter.colorVision applied to the whole canvas when a parameter turns it on |
| ColorWaves | a row of circles colored by a sine wave, with the circles flowing back and forth with time |
| Dithering | a bundled photograph reduced to four extracted colors in six ways: plain nearest-color, ordered Bayer, blue noise, and three error-diffusion kernels |
| Gradients | gradient paint used throughout: a linear gradient for the sky, a radial gradient for the sun, ramps along the path of a Bézier and a polyline, a conic sweep around a ring, and per-vertex shading on a star and a curved shape |
| Harmonies | a base color that drifts, with its complementary, split-complementary, triadic, and analogous palettes, plus the analogous set drawn as a Ramp |
| HSBWheel | a turning HSB color wheel, with hue running around the wheel and saturation growing outward, over a backdrop colored from a hex literal |
| Mixing | the same two colors mixed in RGB, HSB, OKLab, OKLCH, OKHSL, and paint (Kubelka-Munk over spectra), one band per space, with each band's midpoint read back through hue, saturation, and brightness |
| Look | a look from a .cube file wiped across a bundled portrait: the bundled warm print, the identity table, a look written in code, and any .cube file dropped on the window, with the amount on a parameter |
| PaletteFile | palettes read from disk: a CSV file that holds six palettes, and a file with one hex color per line that holds one palette, loaded with no format declared |
| PaletteFromImage | a palette built by clustering a bundled photograph's pixels, a woman before a wall of marigolds, most-used color first |
| PrintSeparation | a sunrise poster split into three spot-ink printing masters, with a halftoned overprint preview and a view parameter that switches between them |
| Shades | four colors taken from a photograph of woven blankets, each grown into a ramp of shades whose hue warms in the light and cools in the shadow, the photograph snapped cell by cell to the nearest shade, and the lightness histograms of both |
| SoftProof | a poster converted into a press profile and back before it is printed, so the colors the ink cannot reproduce show up changed on screen, next to the gamut check and the process plates |
| Swatchbook | the built-in qualitative Palette sets drawn as labeled swatch rows, with a highlight driven by a wrapping index |
