ColorSnapper v2 showing only colors from the background on macOS 10.15 Catalina
In macOS 10.15 Apple added additional privacy permissions. In order for ColorSnapper to work properly it needs to be given the "Screen Recording" permission. You can do this in:
System Preferences → Security & Privacy → Screen Recording
ColorSnapper v1 is lagging on OS X 10.11 El Capitain
ColorSnapper 1 was released back in 2011 and supported for 5 different OS X versions. With the release of ColorSnapper 2 in beginning of 2015 (at that time mac OS “El Capitan” wasn’t even announced) we stopped development and support for the ColorSnapper 1.
The release of the macOS 10.12 “El Capitan” later that year introduced a new rendering engine — Metal. It brought performance improvements for some applications but, unfortunately, made ColorSnapper 1 rendering slow.
In order to fix those issues we would need to make significant changes to the codebase of ColorSnapper 1. This means ColorSnapper 1 will no longer receive updates or bug fixes.
You can try ColorSnapper 2 for 14 days for free — it’s faster and better in every way.
Picking from Adobe Photoshop or Illustrator results in wrong colors
ColorSnapper detects the color profile and automatically converts colors to sRGB to ensure consistent RGB values between your display and your code. To do that, ColorSnapper 2 uses color profile defined in System Preferences. But since Adobe software has a custom color management, ColorSnapper doesn’t know anything about it.
As a work around we suggest that you disable color management for the document you’re picking colors from in the Adobe software.
How can I delete colors from history?
We believe there is no need to delete colors from the history, but if you still want to do so for whatever reason, run this command in the Terminal.app:
defaults delete com.koolesache.ColorSnapper2 HistoryColors
Warning! This will delete all history items and can not be undone.
How can I hide ColorSnapper from the menu bar?
Run the following command in the Terminal.app and restart ColorSnapper.app:
defaults write com.koolesache.ColorSnapper2 showMenubarIcon false
Warning! This will make ColorSnapper accessible only via keyboard shortcuts.
