I made an extension that adds new palettes to the color extension, but when I enter it into my project it stops working. I’ve tried to delete it in java script but it won’t delete. the extension is called arcade-night-palettes

The problem seems to be here… I am not seeing any new colour palettes though.

Ok nevermind I found aa backup project but I’m wondering if there is a way to make custom palettes in the color fading extension; I want to be able to fade between four palettes:  
Original,  
Sunset,  
Evening,  
and Night.

Is there a way to add custom palettes to the color fading extension? @richard would you know how to do this?

@not_a_lemon you can if you go to javascript, click the plus button on top of the file explorer to add a custom ts file, and put this in it:

```auto
namespace color {
    //% fixedInstance whenUsed block="my palette"
    export const myPalette= bufferToPalette(hex`
        000000
        17ABFF
        DF2929
        C600FF
        FF007D
        00FF72
        e5FF00
        0034FF
        FFFFFF
        00EFFF
        FF0000
        7400DB
        636363
        FF7a00
        2D9F00
        000000
    `);
}

```

but save your project before doing that!

It doesn’t cause any problems, the project runs fine, but the palette doesn’t show up in the list.

@not_a_lemon i’ve added the file in this version of the project:

> **[RAIDERS Alpha 0.7 (richard's edit)](https://arcade.makecode.com/33677-23596-09796-16236)**
>
> Made with ❤️ in Microsoft MakeCode Arcade.

note the “my palette” entry in the color fading dropdown.

if you want to add more palettes, go to javascript and click on “custom.ts” in the file explorer:

and declare the palettes in the file just like the one i already added (but with different names). the `//% block=""` annotation can be used to change the name that appears in the dropdown
