From 25e2d2ad97861ca1eb3b327e9d2084c3705bde8b Mon Sep 17 00:00:00 2001 From: Craig Jennings Date: Mon, 15 Jun 2026 18:57:13 -0500 Subject: fix(theme-studio): clamp generated palette spans to the bg/fg bounds Spanning a color generated steps toward pure black and white, so a column could produce colors darker than bg or lighter than fg. I changed regenColumn to ramp the dark side toward the darker ground endpoint and the light side toward the lighter one, bounded by bg and fg. Pure black/white duplicates are still skipped, and callers that pass no ground fall back to the old black/white ramp. Node tests cover the bounded span and the no-ground fallback. The #counttest gate asserts the regenerated column stays within the bg/fg bounds. --- scripts/theme-studio/palette-actions.js | 2 +- 1 file changed, 1 insertion(+), 1 deletion(-) (limited to 'scripts/theme-studio/palette-actions.js') diff --git a/scripts/theme-studio/palette-actions.js b/scripts/theme-studio/palette-actions.js index e65295bc8..4ea8180bc 100644 --- a/scripts/theme-studio/palette-actions.js +++ b/scripts/theme-studio/palette-actions.js @@ -218,7 +218,7 @@ function columnCountControl(f){ // references and leaving removed ones on their now-gone hex.
