Description:

Some charts have rgba colors set by default, but if i want to change it, i can't input another rgba value, neither by typing or copy-pasting.

How to reproduce:

1. Create a chart (I used Polar area cause it had rgba values by default)
2. In a color picker, try to add rgba values

Expected behaviour:

Changing rgba values should work

Current behaviour:

Adding a rgba value doesn't work neither by typing or copy-pasting
