Simple way to hide the "A" field in RGBA / HSLA color picker options

[binaryfire]

Just re-posting this Discord message here as per @andrew-boyd's request:

Hi guys. Enterprise customer here.

We need to be able to hide the "A" field of the RGBA / HSLA inputs in the color picker. There are some parts of our app where we don't want to allow users to set transparency.

Is there a clean way of doing this? Or if not, would it be possible to add one? Screenshot attached.

PS. This is a pretty common requirement in visual editors. There are a lot of times when you don't want users to have access to the transparency value.
