Color field migration from RGBA

[mynameisfreedom]

Hi team, as always your new features are great, and it is fantastic that the Color field is in the core.

Description

But I have one issue with migration from hananils/kirby-colors plugin to the new Color field. Migration to the Color field is smooth except for one thing: hananils/kirby-colors plugin used rgba color when alpha is set to true. So, at the moment it is not possible to migrate those to the Kirby Color field.

hananils/kirby-colors saved alpha: true fields in this format rgba(0,0,0,0.3) so when I migrate to new Color field there is an error for every field that used opacity. And because every Layout Builder section in my Layout Builder has a color opacity overlay option for the section background image, that field is used a lot. 🫣

Expected behavior

If you could either:

• add a script to change rgba inputs into new rgb format (example: rgba(0,0,0,0.3) into rgb(0 0 0 /0.3)) on save
• or add support for legacy rgba colors

hananils/kirby-colors still work, but I doubt that will be the case for too much longer.

Maybe this is a small thing, but it would help hundreds of websites migrate smoothly to the new Color field.

Thank you in advance. 🙏

I thought this would already work. Have you the alpha: true option set? https://getkirby.com/docs/reference/panel/fields/color#alpha

[mynameisfreedom]

Yes, I have alpha: true option set but it still gives me an error during saving in the panel.

Maybe your script don't support rgba(0,0,0,0.3) but support rgba(0, 0, 0, 0.3). I will see to test this.

Hmm, now in my test everything went smoothly... It migrated the color properly. And a few hours ago it gave me an error on every try.

You can feely close this, I will go for further migration.

Ah, on further migration I do get an error. Please leave this open, I need to explore more on why this is happening

[mynameisfreedom]

Sorry for the delay. I think I found what is making an error.

The new Kirby color field only supports one format at a time (hex or RGB or HSL), but old Kirby colors plugin supported all formats at once.

For the same field in the Layout section on one page admins often used hex colors if the color is not transparent and RGB if the color is transparent. In that case, Kirby's color field drops an error for a color format it doesn't support. So, to make the migration, the admin would need to go from field to field and manually change color to get the supported format.

I reverted to the old Kirby colors plugin fields all fields with alpha: true, for the time being.

Could you do something about this?
Can you make a new Kirby Color field, for example: although it has format: hex and the old field value is RGB, don't report error, but convert the RGB value to hex? Or just don't throw an error?
