Hello,

I would like to write code that can change the color of a simple clipart file. That is, I don’t want to be limited to the icons available. I thought I could use the setStyle function - but I can’t figure it out.

Any help would be greatly appreciated!

Thanks.

To change the color of clipart you will need to have a transparent background image. Then, you can do something like the following with setStyle()

setStyle(“image1”, “filter: invert(19%) sepia(92%) saturate(7063%) hue-rotate(358deg) brightness(94%) contrast(110%);”);

You can use this site to figure out the values for filter based on the color you want: [https://isotropic.co/tool/hex-color-to-css-filter/](https://isotropic.co/tool/hex-color-to-css-filter/)

Thank you so much for your help. At first I could not get the call to setStyle to work - but when I changed the double quotes to single - it worked.

The website is also very helpful!

I have made an app that allows the user to select a shape and use it as a stamp on the canvas. I will now add a drop down to select color and will also move the canvas to a different screen.

Thanks again!
