HTML color picker not supported?

I am trying to make an input type color () in my app for the user to pick a color, but it’s not opening the color picker for some reason.
Is it not supported in Overwolf? and if that is the case what alternative do i have?

So you are right, we are not supporting the color picker, as this control is part of the operation system. We might add support for it in the future (like we added the file picker control), but currently you can’t add color picker control in an overwolf app. Having said that, you can easily use an implemented version of a color picker.
