Feles

Feles is a set of soft, dark and light themes in four cat coats:

Coat	Accent
Cinnamon	Cherrywood Red
Russian Blue	Teal
Siamese	JetBrains Blue
Marmalade	Gold

All four share the same low-contrast UI and italics, and each comes in a Dark and a Light version.

To install:

Open Extensions on the sidebar.
Search for Feles.
Install & reload.
⌘ + ⇧ + P and type "Color Theme".
Pick a Feles theme from the list, for example Feles Siamese Dark, and hit enter.

To switch between the dark and light version with your system theme, add this to your settings:

"window.autoDetectColorScheme": true,
"workbench.preferredDarkColorTheme": "Feles Siamese Dark",
"workbench.preferredLightColorTheme": "Feles Siamese Light"

Coming from Gatito Nightly

Feles used to be called Gatito Nightly. The Red and Blue themes are now Cinnamon and Russian Blue, and keep their old setting names so existing settings keep working:

Theme	Setting name
Feles Cinnamon Dark	`Gatito Nightly Red`
Feles Cinnamon Light	`Gatito Daylight Red`
Feles Russian Blue Dark	`Gatito Nightly Blue`
Feles Russian Blue Light	`Gatito Daylight Blue`

Use these names for Cinnamon and Russian Blue in settings like workbench.preferredDarkColorTheme.

Siamese

Siamese is inspired by JetBrains IDEs. It uses the JetBrains blue accent and the code colors of JetBrains' Islands Dark and IntelliJ Light schemes, including their semantic highlighting: fields in purple, declarations colored and calls left plain.

For the full look, these settings go well with it:

"editor.fontFamily": "JetBrains Mono",
"editor.fontLigatures": true,
"workbench.tree.indent": 12,
"editor.bracketPairColorization.enabled": false

Marmalade

Marmalade pairs its gold accent with the code colors of Ayu.

Credits

Feles started as a fork of Gatito Theme. Siamese's code colors come from the JetBrains Islands Dark and IntelliJ Light schemes, and Marmalade's from Ayu.
