From 25bfd29cd4be84dbddac21ee06563cdee46484c6 Mon Sep 17 00:00:00 2001 From: Craig Jennings Date: Fri, 22 May 2026 17:03:24 -0500 Subject: chore(themes): regenerate dupre palette preview from palette.el The committed palette PNG had drifted from the theme. It labeled steel as "cyan", invented magenta colors the palette never had, and left out blue+2. There was no generator, so the preview and the source diverged silently. I added gen-palette-preview.py, which parses the (name "#hex") pairs straight out of dupre-palette.el and emits the preview HTML grouped one row per color family. I regenerated the HTML and the PNG from it, so all 32 colors show with square swatches at 2x, columns aligned, and nothing drifts from palette.el again. --- themes/gen-palette-preview.py | 83 +++++++++++++++++++++++++++++++++++++++++++ 1 file changed, 83 insertions(+) create mode 100755 themes/gen-palette-preview.py (limited to 'themes/gen-palette-preview.py') diff --git a/themes/gen-palette-preview.py b/themes/gen-palette-preview.py new file mode 100755 index 00000000..0b15f10b --- /dev/null +++ b/themes/gen-palette-preview.py @@ -0,0 +1,83 @@ +#!/usr/bin/env python3 +"""Generate the Dupre palette preview HTML from dupre-palette.el. + +Reads the (name "#hex") pairs straight from the palette source so the preview +can't drift from the theme.
