This tool is mainly focused on UI design and creating color systems where you have specific requirements for colors like contrast and interchangeability.
Coming up with color families is still somewhat about feeling it out and playing around, but when it comes to then creating scales from these, that's where Atmos comes in handy.
I use tools like this to generate html codes for colours I want, that make sense together. I don't need tools like this often enough to want to to pay or even sign up for it when there are literally hundreds of identical offerings out there for free.
I sometimes use Adobe Color (which is very similar to this) to come up with new palettes when I’m stuck and want something different. Sometimes it works out and sometimes it doesn’t, but it’s another point of inspiration.
When I come up with color palettes, it's intuitive and guided by a sense of play and feeling it out. I wouldn't use this.
Do professional designers use tools like this now? Or does this target non-artists? I'm curious.
