Features
Lumi’s feature set is focused on digital painting and structured illustration workflows, built on non-destructive, layer-based editing.
This section describes the core capabilities available in Lumi and where to locate them in the interface.
Save warmed-up caches for favourite brushes so they feel fast as soon as possible.
Open container format storing layers, metadata, ICC profiles, and recovery data.
Automatic incremental recovery snapshots protect work against crashes and power loss.
Layer-based compositing with blend modes, masks, groups, and non-destructive adjustment layers.
Pressure, velocity, tilt, and spacing dynamics with stabilization, smoothing, and multi-head brush formations.
Create and manage named pigment palettes, with bundled sets covering full-spectrum and limited palettes.
Interactive 2D grid mapping palette pigments to axes, used for direct color picking and exploration.
Mix pigments from the active palette by hue, saturation, and tone with visual gap previews.
Automate workflows and extend Lumi using an embedded Scheme interpreter.
Physically accurate pigment mixing using spectral upsampling, producing realistic paint behaviour.
Displace pixels freely with brush strokes. Warps entire layer groups as one item, applying the same transformation to all nested layers and masks.
Save and switch complete UI environments: panel layouts, tool settings, device configuration, theme, and palette — independently per workspace.
