Chrome Dev Tools RGBA/HSL Conversion to some new format

Question

I used to convert #1c1959db to the standard rgba(255,0,0,0.3) but now it converts to some unrecognized format rgb(28 25 89 / 86%). please guide how to fix this on chrome dev tools

Answer 1

but now it converts to some unrecognized format rgb(28 25 89 / 86%).

This is the new format as defined in the specification

rgb() = rgb( <percentage>{3} [ / <alpha-value> ]? ) |
        rgb( <number>{3} [ / <alpha-value> ]? )
<alpha-value> = <number> | <percentage>

You should get used to it now but you can easily convert to the old format like below:

 rgb(28 25 89 / 86%) ---> rgba(28,25,89,0.86)

All you have to do is to add the comma seperation and transform the percentage of the alpha channel to a number between 0 and 1
