These are my theme settings in src/admin/app.js.
export default {
config: {
theme: {
colors: {
primary100: '#eff8f7',
primary200: '#c4f0eb',
primary500: '#8ae2d6',
primary600: '#60bdb2',
primary700: '#0a7a7f',
},
}
}
}
Now, it does override all of them, except for the last one for some reason, as you can see in the image below, the button is still purple.
