Enable rgba Colors

[SeanBlakeley]

It'd be great if the color picker could output a rgba color and offer users an opacity option.

Cheers,

Sean.

The underlying color library already speaks rgba fluently, it's just that the UI doesn't have an opacity slider.

Agree, that would be an awesome improvement to have rgba() :) It's good to hear that it's almost there. Thank you for making this great colorpicker!

I would love to see this featured added to Iris. Possibly even an option to allow for a transparent value as well as noted here - http://core.trac.wordpress.org/ticket/21059#comment:7

Trying to add opacity to my theme i'd like to add my vote. Unfortunately i am not a programmer but i found some input which might be helpful:

• convert hex to rgb
• convert hex color to rgb using php
• background manager contains a slide controller for the WP Theme Customizer

I totally agree with this. A secondary slider for transparency like Minicolors does would be good.

The change callback would have to be updated as well, providing the alpha value.

Hello,

This issue was opened a year ago, are there any news about implementing an opacity slider?

Thanks!

[riccardobianconi]

As far as I know, there are no news about it.

[mattwiebe]

The news is simple: neither the WordPress project nor I have needed this, so there are no plans for me/us to do this at present.

Of course, this is open source: anyone could implement it and submit a PR. I would be open to working with them to get it to a merge-able state.

I have created a short tutorial on how to implement alpha/opacity support. Please check it out
