In this case, when the shell is `pwsh`, the `latte` palette will be used, otherwise it uses the `frappe` palette. If you want,
you could also add `frappe` as the default `palette`, given that one is used as a fallback when not match can be found based on what
the `template` resolves to. In case no match is available and no `palette` is defined, it will also fallback to `transparent`
for any palette color reference in templates/colors.
If you want to avoid color duplication, you can use palettes in combination with the `palette` property. This way you can define
a color once and reuse it in multiple palettes. For example:
<Config
data={{
palette: {
black: "#262B44",
green: "#59C9A5",
orange: "#F07623",
},
palettes: {
template: '{{ if eq .Shell "pwsh" }}latte{{ else }}frappe{{ end }}',
list: {
latte: {
red: "#e64553",
white: "#E0DEF4",
yellow: "#df8e1d",
blue: "#7287fd",
},
frappe: {
red: "#D81E5B",
white: "#E0DEF4",
yellow: "#F3AE35",
blue: "#4B95E9",
},
},
},
}}

If a color is defined in both palette and palettes, the palettes' resolved color will take precedence.

## Cycle
When you want to display the same **sequence of colors** (background and foreground) regardless of which segments are active, you can
make use of the cycle property. This property is a list of colors which are used one after the other in a continuous loop. A defined
cycle always gets precedence over everything else.
```json
...
"cycle": [
<Config
data={{
cycle: [
{
"background": "p:blue",
"foreground": "p:white"
background: "p:blue",
foreground: "p:white",
},
{
"background": "p:green",
"foreground": "p:black"
background: "p:green",
foreground: "p:black",
},
{
"background": "p:orange",
"foreground": "p:white"
}
background: "p:orange",
foreground: "p:white",
},
],
...
```
}}
