Scale (by Hayk An) is a free, open-source color scale generator: pick a start and end color and it builds the tints and shades between them, with controls for darkness, lightness, angle, and saturation.
Every setting change updates the shareable URL, so an exact scale configuration, not merely a screenshot, can be sent to a teammate or dropped into design documentation for someone else to open and adjust further.
Designers and developers building data-visualization color scales (like a heatmap or chart gradient) who need precise, shareable control over the tints between two colors.
Copy the SVG output directly if the scale needs to live as a design asset, rather than manually recreating each shade as separate swatches.
