Icon

The RGB color cube a .cube LUT indexes, seen from its green corner with black at the front bottom, on the same near-black ground as the app's canvas. Faces are true bilinear color interpolation, rendered by scripts/render-icon.swift (CoreGraphics only) into every macOS slot of the appiconset. A faint rim light on the two bottom edges keeps the silhouette on dark desktops. Reads as a cube at 16 px.

Release script

scripts/release-dmg.sh <version> builds the universal executable, wraps it in LUTzy.app with the icon and an Info.plist, signs with Developer ID and the hardened runtime, notarizes and staples the app, builds the DMG, and notarizes and staples that too. Same order as the rapple release script. build/ is now gitignored.

Used to produce the v0.1.0 DMG with the icon.

The icon is the RGB colour cube a .cube LUT indexes, viewed from its green corner with black at
the front, on the app's near-black canvas. scripts/render-icon.swift draws it in CoreGraphics
with exact bilinear face colours and writes every macOS slot into the appiconset.

scripts/release-dmg.sh does what an Xcode archive would, since Package.swift has no app target:
universal build, hand-written bundle with the icon, Developer ID + hardened runtime, notarize and
staple the app, DMG, notarize and staple the DMG.
