+
+## Theme
+
+Many browsers automatically turn on "night mode" to lower the light emission of the screen. Users can override the browser theme in their settings menu.
+
+In both "dark mode" and "light mode", the colors must provide adequate contrast and consistency.
+
+## Semantic colors
+
+We use semantic color variables that can mean a different shade depending on the currently chosen theme
+
+- primary
+- secondary (default)
+- destructive
+
+## Color variants
+
+For each semantic color, we set a foreground and a background. In addition, we need to check context: A button should have a stronger shade when the mouse is hovering over it. When a surface is raised over another surface, it should have a stronger shade, too.
+
+- ghost (default for most other things)
+
+  - text color
+
+- outline
+
+  - border color
+
+- solid (default for buttons)
+  - bg color
+  - border color
+
+Variants can be made interactive and/or raised:
+
+- no alteration (default)
+
+- raised
+
+  - text color
+  - border color
+  - bg color
+
+- interactive
+
+  - can be disabled
+  - can be active
+  - can be exact-active
+  - can be hovering
+
+- interactive-raised
+  - combine `raised` and `interactive`

+## Limitations of component props
+
+While Vue can infer props based on a type, it will fail with mysterious errors if the type is an exclusive union or has union types as keys.
+
+I hope this will be resolved soon so we can use this more elegant way of injecting non-trivial props with full autocomplete, 21st century style:
+
+```vue
+<script setup>
+type A = 'either' | 'or'
+type B = 'definitely'
+type Props = { [k in `${A}-${B}`]?: true }
+</script>
+
+<template>
+  <Component either-definitely />
+  <Component or-definitely />
+  <Component />
+  {{ Error: <Component either /> }} {{ Error: <Component definitely /> }}
+</template>
+```
+
+::: details Example
+
+````ts
+// Color from props
+
+type SingleOrNoProp<T extends string> = RequireOneOrNone<Record<T, true>, T>;
+type SingleProp<T extends string> = RequireExactlyOne<Record<T, true>, T>;
+
+export type Props = Simplify<
+  SingleProp<Color | Default | Pastel> &
+    SingleOrNoProp<Variant> &
+    SingleOrNoProp<"interactive"> &
+    SingleOrNoProp<"raised">
+>;
+
+// Limit the choices:
+
+export type ColorProps = Simplify<
+  SingleProp<Color> & SingleOrNoProp<Variant> & SingleOrNoProp<"raised">
+>;
+
+export type PastelProps = Simplify<
+  SingleProp<Pastel> & SingleOrNoProp<"raised">
+>;
+
+// Note that as of now, Vue does not support unions of props.
+// So instead, we give it a single string:
+
+export type ColorProp = Simplify<`${Color}${
+  | ""
+  | `-${Variant}${"" | "-raised"}`}`>;
+export type PastelProp = Simplify<`${Pastel}${"" | "-raised"}`>;
+
+// Using like this:
+//   type Props = {...} & { [k in ColorProp]? : true }
+// This will also lead to runtime errors. Why?
+
+export const isColorProp = (k: string) =>
+  !![...colors, ...defaults, ...pastels].find(k.startsWith);
+
+console.log(true, isColorProp("primary"));
+console.log(true, isColorProp("secondary"));
+console.log(true, isColorProp("red"));
+console.log(false, isColorProp("Jes"));
+console.log(false, isColorProp("raised"));
+
+/**
+ * Convenience function in case you want to hand over the props in the form
+ * ```
+ * <Component primary solid interactive raised >...</Component>
+ * ```
+ *
+ * @param props Any superset of type `Props`
+ * @returns the corresponding `class` object
+ *
+ * Note: Make sure to implement the necessary classes in `colors.scss`!
+ */
+export const colorFromProps = (props: Record<string, unknown>) =>
+  color(
+    Object.keys(props)
+      .filter(isColorProp)
+      .join(" ")
+      .replace("-", " ") as ColorSelector,
+  );
