[FEATURE REQUEST] Update the color picking tool to be more intuitive and user-friendly #943

Problem

I've been using devicons a few times now, and only today did I find out that there's a color-picker to select a background color for the icons. This is (in my opinion) due to bad design, since the icon for picking a color is no self-explanatory. While I was looking at the color picker I also found a few other things I think can be improved (explained under the "Suggested feature" section.)

Suggested feature

Here's a list of the features I think are either missing, or can be improved:

1. Like I've already mentioned, the color picker icon should be changed to something more self-explanatory, like this or this
2. Currently there is no way to change back to a transparent background. There should be an option to change the alpha/transparency of the color. Maybe just a tick box, and an extra input field for each "manual" color picking option (RGB->RGBA, HSL->HSLA, and Hex should be #AARRGGBB instead of #RRGGBB).
3. Unlike the other two points, this is just a nice-to-have, but it would be nice to have a "checkered" alternative

Why should we have this feature?

This would improve the over all User Experience, and would result in a more polished product.
