*.kpl

自 4.0 版开始 Krita 启用了一种全新的调色板文件格式。它支持宽色域颜色，包括 RGB、CMYK、XYZ、GRAY、和 LAB 等，也兼容任意一种色彩位深度，还可以对颜色进行分组。这便是 Krita 调色板文件，或 *.kpl。

*.kpl files are ZIP files, with two XMLs and ICC profiles inside. The colorset.xml file contains the swatches as ColorSetEntry and Groups as Group. The profiles.xml file contains a list of profiles, and the ICC profiles themselves are embedded to ensure compatibility over different computers.
