How to set transparency with hex value ?

For example, you want to set 50% alpha transparency to #000000 (black color), you need to add 66 like this #80000000

While using Zeplin, sometimes designer just add Opacity/Alpha to any color and Hex code to it is not present.

In this example, you see that “Black” color is present but carefully looking at the “Opacity” parameter, it is “60%”. If you convert this color to equivalent one, it will be “#99000000”.

Below table gives you very straight forward Hex code for percentage used in Zeplin.
