Discover the hexadecimal color code generated from an rgba color

Do you know of a service that can determine the final hexadecimal value of an rgba color? For instance, if my body background-color is set to #FF0000 and my header is positioned over it with a background-color of rgba(0,0,0,.7), how can I find out what the resulting hexadecimal value of this color mix is?

Any suggestions on how to accomplish this?

Appreciate your help.

Answer №1

With SASS, you have the ability to preprocess your CSS and have it automatically calculate values for you.

In this example, I started with the base color #FF0000 and darkened it by 70%.

If you're interested, here is a code pen I created using SASS: http://codepen.io/anon/pen/ozlHD

The resulting hex value of the div is #4C0000, which is the correct calculated value.
