as far as I know, you can’t add custom palettes to the drop down menu

however, you can fade colours individually so its possible to fade all 15 colours to a different palette

@WoofWoof was working on making some additions to the colour fading ext, might add the custom palette feature if i beg hard enough :heart:

a block to adjust the HSV, a block to enter in custom palettes for the fading and a block to set brightness/darkeness levels across the entire screen

That is interesting. I wonder if they edited the extension’s code. Could you send the project you are referring to so I could take a look?

i think it’s possible, you have ti go into the extension itself through java and add all your colors manually there

you can do this in js

namespace color {
     */
    //% fixedInstance whenUsed block="CoolNameHere"
    export const CoolNameHere = bufferToPalette(hex`
        000000
        000000
        000000
        000000
        000000
        000000
        000000
        000000
        000000
        000000
        000000
        000000
        000000
        000000
        000000
        000000
    `);

It wont show up as a enum in the block in blocks BUT you can use that palette in js like this test project

an alternative is to make a fork of jwunderl’s extension and add custom palettes in palettes.ts with the aforementioned method and then import your fork into the project this method will show an enum in blocks.( I feel big brain somehow)
