Windows窗体：仅彩色对话框纯色

Question

在检查Windows窗体的ColorDialog上的选项后，我想知道将SolidColorOnly属性设置为true或false（换句话说，什么是纯色 ，什么不是纯色 ）之间的区别。

Answer 1

If you want to know what solid color means, then the question could be "What solid color means?".

A solid color means that all pixels have the same color. For a single pixel it doesn't make much sense, but a larger area can be colored with some kind of raster consisting of pixels in more than one color. When such area is viewed from a distance, it almost looks like another color.
