[enhancement]: Black color causes viewing/UX issues

[filippo-fonseca]

The following is an example of how the black color rendering causes an issue for the user's UX:

In my opinion, this can be enhanced by allowing the user to clearly distinguish and denote where the shape is, even if the color may be black.

My opinion is that if the user sees that the shape is not visible, it should tell him not to use the particular color combination. If there will be something that will show the shape even though it is not visible, it might result in people not using the generator correctly and that would result in bad UX on their websites.

It's quite logical that a pitch-black background neither reflects light nor allows for distinguishing the shadow thrown at it. A shadow is an absence of light. In real life, when a surface consumes all the light that's directed at it, no shadows would be visible
