Color Finder

This app helps me match colors from photos for my art work. It has a nice range of helpful information included with each color pick. It saves me from having to look at my color wheel when I want information about the color choosen. I find it very useful although it could also be used to match colors when you need them for an online project with the information that is gives. I like it. I am also interested in saving the color palettes if there were a way. Something for a future version maybe?

Pretty! but buggy, and both the app and dev are unresponsive

Performance: when dragging around sliders, Color UI will only update at around 0.5–2 FPS! This is not that computationally intensive a task, and it feels really unpleasant.

Bugs: The app will straight-up provide incorrect information. If you adjust the brightness or saturation, for example, the hex value will often be a completely different color.

Additionally, I spent over an hour writing a detailed bug report, which I sent the developer nine months ago. I followed up six months later, since I hadn't heard anything. I still haven't heard anything, and despite having received multiple updates in that time, none of the issues I reported have been resolved.

This could be a nifty little app, but for now, I'd recommend steering clear.

Useful and Thorough

Great for when I quickly need a HEX color translated into RGBA for CSS or UIColor for Xcode.
If I can suggest a new feature, I’d love to see it be able to save/load Color Palettes stored in the Apple Color Picker.
