Forest Cozy — Wovi10

First working version, built directly from the "Forest Cozy" terminal color palette.


| Firefox property | Hex | Source in palette | Reasoning |
|---|---|---|---|
| frame / frame_inactive | #1a1f1a | background | Base window color, used as-is |
| toolbar | #242a24 | derived (lightened background) | Needed a shade between background and brightBlack so the toolbar reads as a separate surface, not flat with the frame |
| toolbar_field | #1a1f1a | background | Address bar recessed into the frame color, standard convention |
| toolbar_field_focus | #242a24 | derived | Matches toolbar, so focus doesn't look like a different theme |
| tab_selected | #2a312a | derived (lightened background) | Lightest of the three near-black tones, so the active tab is clearly the brightest of frame/toolbar/tab |
| tab_background_text | #c9c9b8 | white | Muted for inactive tab labels, keeps focus on the active tab |
| tab_text | #e8e6d9 | foreground | Full contrast for the active tab's label |
| tab_line | #8a9a5b | green | Active-tab accent underline; green read as "alive/active" fit the forest theme better than red or yellow |
| tab_loading | #8a9a5b | green | Matches tab_line so the loading state doesn't introduce a new color |
| icons | #c9c9b8 | white | Slightly muted so icons don't compete with active text |
| icons_attention | #c9a86a | yellow | Warm, attention-drawing tone for permission/update badges |
| popup, sidebar | #1a1f1a | background | Consistent recessed surfaces |
| popup_text, sidebar_text, ntp_text, bookmark_text | #e8e6d9 | foreground | One consistent text color across all surfaces |
| borders/separators (*_border, *_separator) | #3a413a | brightBlack | Palette's own "next step up from background" tone — used everywhere a subtle line is needed |
| button_background_hover | #242a24 | derived | Matches toolbar tone for consistency |
| button_background_active | #3a413a | brightBlack | Slightly stronger than hover, for pressed state |

• Only two "derived" colors were introduced (#242a24 for toolbar surfaces, #2a312a for the selected tab). Everything else pulls directly from your palette. This keeps the theme tightly tied to "Forest Cozy" rather than drifting into arbitrary new colors.
• Green was chosen as the single accent (tab line, tab loading) rather than spreading multiple accent colors across the UI. A theme with one consistent accent reads as more intentional than one that uses green here, yellow there, blue somewhere else.
• No image assets (theme_frame) in this version — colors only. Keeps the theme lightweight and easy to tweak by editing hex values directly.

• Firefox's private browsing window uses a slightly different rendering path for some properties (toolbar in particular); the current theme hasn't been visually verified in a private window.
• Contrast between tab_background_text (#c9c9b8) and toolbar/frame should be checked against WCAG AA if accessibility matters to you — it looks fine visually but hasn't been measured.
• No dedicated "new tab page" image or accent — currently just background/foreground colors on ntp_background/ntp_text.
