Recolor desert farm Stommel with colorblind-safe earth tones#28
Merged
Conversation
ENERGY_COLORS palette swapped for a muted earth-tone palette tuned for deuteranopia/protanopia separation by luminance: Chemical #0F793D (forest green) -> #7A8C5C (olive, L≈129) Radiative #FFCC33 (gold) -> #E5C16E (warm sand, L≈194) Thermal #CC3333 (red) -> #7B3F3F (deep rust, L≈81) Mechanical #336699 (steel blue) -> #4F6B82 (slate, L≈101) All pairwise luminance gaps >=20 -> distinguishable in grayscale and under all three CVD types. Footer link color updated to match. Regenerated docs/desert_farm_stommel.html.

The merge of PR #30 (refactor) resolved its conflict with PR #28 (earth tones) by taking the refactor branch's old ENERGY_COLORS values (#0F793D / #FFCC33 / #CC3333 / #336699), reverting #28's earth-tone palette in the dict. The CSS footer link color was preserved as #7A8C5C, leaving the file in an inconsistent state where the legend swatches and ellipse fills used the old palette while the page accent used the new one. Restoring the earth-tone palette and regenerating the HTML: Chemical #0F793D -> #7A8C5C (olive) Radiative #FFCC33 -> #E5C16E (warm sand) Thermal #CC3333 -> #7B3F3F (deep rust) Mechanical #336699 -> #4F6B82 (slate) Same palette and same colorblind-safety reasoning as PR #28.

* fix: restore earth-tone palette in ENERGY_COLORS after PR #30 merge The merge of PR #30 (refactor) resolved its conflict with PR #28 (earth tones) by taking the refactor branch's old ENERGY_COLORS values (#0F793D / #FFCC33 / #CC3333 / #336699), reverting #28's earth-tone palette in the dict. The CSS footer link color was preserved as #7A8C5C, leaving the file in an inconsistent state where the legend swatches and ellipse fills used the old palette while the page accent used the new one. Restoring the earth-tone palette and regenerating the HTML: Chemical #0F793D -> #7A8C5C (olive) Radiative #FFCC33 -> #E5C16E (warm sand) Thermal #CC3333 -> #7B3F3F (deep rust) Mechanical #336699 -> #4F6B82 (slate) Same palette and same colorblind-safety reasoning as PR #28. * Update header description to match earth-tone palette The page header had 'chemical (green), radiative (gold), thermal (red), mechanical (blue)' baked into the prose. After the palette change to olive/sand/rust/slate, that text would describe colors that no longer match the rendered ellipses.
