Alpha Color

[yussefbens]

Hi, I'm using your lib and I love it so much, but when I want to add 100% alpha color it just doesn't appear it's a full transparent color.
Thank you and sorry for creating the issue "Hi,", it was a mistake.

Thanks for the report. Can you give an example of the code or color hex value that's producing this problem?

What I want to say is not for a specific color but for all colors that contain #00XXXXXX, I want to be something like in attachment

Spectrum wasn't really designed to work with semi-transpatrent colors, so in this case it's working as intended. You're more than welcome to submit a pull request implementing your desired feature!

Spectrum does work with semi-transparent colors but they look 'washed out' as the white background is blended into the color. One issue I've found is that the code that decides to draw a white or black border around the color swatch only looks at RGB, so 00000000 and 00FFFFFF have different colored border but each swatch looks 'white' as the background color blends through.

My guess is that having a checked background like was suggested would obviate the need for borders on transparent items over a certain threshold. If/when we get that done, we can see how best to calculate borders for semi-trasparent colors.

True enough but, depending on usage, we may not want a checked background so I think the issues are separable. In my case, I have a "highlight" color dialog for highlighting text. Showing the highlight just the way it's going to look works well for us:
