I would love to share with you this link:
I created this tool to generate colour variants, it’s different from any other similar product because it allows to choose exactly how to make darker and lighter colors. For instance for a darker shade of orange it’s possible to decide to make it more red or keep the same hue but darker.
The darker colors are not made by mixing black at a certain level of opacity but by reducing the luminance, which creates much more vibrant and interesting results.
It’s also easy to use with its visual controls but still very powerful. (Basically you can move the handlers to adjust a bezier curve and pick all the different colours thanks to this curve)
Whenever satisfied by the scale created (can have up to 10 variations) the tool allow to export all of them to sketch or the most common code languages.
I hope you will have time to take a look at it and share some feedback with me. I just started the project and I would love to keep improving it overtime.
