- ColorScheme::Bwgbryo = 8: 7-color ACeP, color order = panel native nibbles (black0 white1 green2 blue3 red4 yellow5 orange6) - INKPLATE_6COLOR measured palette (nominal RGB; TODO measure) in CATALOG - Python ColorScheme.BWGBRYO mirror + INKPLATE_6COLOR export - Tests: palette count=7, value=8, native-order guard Verified: pure colors dither to indices [0..6] matching the panel nibbles.

Hardware calibration: the panel's raw inks photograph very desaturated (green contaminated by ghosting), so nearest-color matching sent vivid greens->yellow and blues->black. Replaced with hue-representative values so all 7 source colors select the correct ink (verified: pure swatches dither to nibbles 0..6). The panel still renders its own (muted) ink per nibble; these values only drive matching. TODO: precise tone-accurate measurement on a ghosting-cleared panel.

Closing this because we are no longer pursuing the OpenDisplay integration path for Inkplate 6COLOR. The BWGBRYO palette work was useful for the proof of concept, but the chosen Home Assistant path is now Soldered's ESPHome component: https://github.com/SolderedElectronics/Soldered-Inkplate-ESPHome. Keeping this PR open would add an unused OpenDisplay host-rendering path for a board whose supported stack renders locally in ESPHome. |

Summary
Adds a 7-color ACeP color scheme for the Soldered Inkplate 6COLOR (600×448, panel_ic_type
0x0043):ColorScheme::Bwgbryo = 8(Rust corepalettes.rs+ Pythonpalettes.py). Color order matches the panel's native nibble codes:black0 white1 green2 blue3 red4 yellow5 orange6— so dither indices map directly to panel nibbles (no remap, unlikeBwgbry).INKPLATE_6COLORmeasured palette inmeasured_palettes.rs+CATALOG, exported in the Python package.Testing
cargo test— 44 core tests pass (incl. the new ones).[0..6]matching the panel nibbles.Note: palette is nominal (calibration TODO)
The
INKPLATE_6COLORRGB values are nominal placeholders (marked TODO, likeMONO_4_26/BWRY_4_2). On hardware, saturated greens/reds currently match to the nearest nominal ink (green tends toward yellow). Measuring the actual panel inks (as theSPECTRA_7_3_6COLORentries were) will sharpen hue accuracy — happy to follow up with measured values.Related
