Plan Paint 1.0 — Native Forms, gradients and a new name

Plan Paint 1.0 is the new name of Rainstar Paint. The native GUI.Forms application is now the primary and only released frontend. The older SDL/ImGui frontend is deprecated and remains available in source for historical comparison.

This release includes the new brush-pot icon and refreshed in-app Help and About documentation, including Jeremiah 29:11:

"For I know the plans I have for you, declares the LORD, plans to prosper you and not to harm you, plans to give you hope and a future."

Changes in 1.0:

• Gradient bucket fills: linear with angle or circular, 2–32 movable color stops, per-stop transparency, reverse, and twelve presets including rainbow, fire, electric blue, chrome, gunmetal and galaxy.
• Interface hue settings, tighter ribbon spacing, atomic saving and crash recovery.
• Refined OKLab dithering and posterization, with the independent dithering brush retained.
• Spirograph guides, inserts and media pegs; gel pens, custom pattern canvas, native cursors, Carpet textures, persistent selections and working-view rotation.

Install the macOS package, or extract the complete Windows/Linux archive. Run plan-paint.exe on Windows or Plan Paint on Linux. Existing preferences, palettes, patterns and recovery data remain available; internal storage and the macOS application identifier retain compatibility with earlier releases.

The Mac app requires Apple Silicon and macOS 26 or newer. It is ad-hoc signed, without Developer ID notarization. Linux requires X11 or XWayland; native Wayland and mixed-DPI Linux are not supported. Windows 7 operating-system compatibility is not claimed.

See verification.json for platform-specific checks and SHA256SUMS for package integrity. The application, source code and original artwork are available under the MIT license; dependencies retain their own notices.
