How to tweak the theme
Flat-Plat is a complex theme, so to keep it maintainable it's written and processed in SASS.
It is very likely your change will happen in the _common.scss file. That's where
all the widget selectors are defined. Here's a rundown of the "supporting"
stylesheets, that are unlikely to be the right place for a drive by stylesheet
fix:
_colors.scss
global color definitions. We keep the number of defined colors to a necessary minimum, most colors are derived form a handful of basics. It covers both the light variant and the dark variant.
_colors-public.scss
SCSS colors exported through gtk to allow for 3rd party apps color mixing.
_drawing.scss
drawing helper mixings/functions to allow easier definition of widget drawing under specific context. This is why Flat-Plat isn't 15000 LOC.
_common.scss
actual definitions of style for each widget. This is where you are likely to add/remove your changes.
You can read about SASS at http://sass-lang.com/documentation/. Once you make
your changes to the _common.scss file, run the ./parse-sass.sh script.
How to change the assets color
To keep it maintainable SVG files are basically edited on text-based.
So if you just want to change the SVG assets color, I recommend using a text editor instead of Inkscape. But please note that in some cases Inkscape is needed to render PNG assets.
Here is an example to change the _accent color_:
Open the following
.svgfiles with a text editor.
- ./src/gtk-2.0/assets.svg - ./src/gtk-2.0/assets-dark.svg - ./src/gtk-3.0/gtk-common/assets.svg - ./src/gnome-shell/3.18/assets/checkbox.svg - ./src/gnome-shell/3.18/assets/more-results.svg - ./src/gnome-shell/3.18/assets/toggle-on.svg - ./src/gnome-shell/3.18/assets-dark/checkbox.svg - ./src/gnome-shell/3.18/assets-dark/more-results.svg - ./src/gnome-shell/3.18/assets-dark/toggle-on.svg
Search
#FF4081(default accent color) and replace with your favorite color.
- The recommended color palette is: https://material.io/guidelines/style/color.html#color-color-palette
For gtk2 and gtk3, delete all png assets before redrawing them.
sh
rm -v ./src/gtk-2.0/assets/*.png
rm -v ./src/gtk-2.0/assets-dark/*.png
rm -v ./src/gtk-3.0/gtk-common/assets/*.png
Render png assets with scripts. (Inkscape is required to run the scripts.)
- for gtk2:
sh
cd ./src/gtk-2.0
./render-assets.sh
./render-assets-dark.sh
- for gtk3:
sh
cd ./src/gtk-3.0/gtk-common
./render-assets.sh
