Excel VBA —三个连续的单元格具有相同的interior.colorindex，但是这三个单元格的范围返回不同的颜色

Question

我有三个连续的单元格（A1，B1，C1），它们的internal.colorindex均为15。但是，如果我检查是否cells（A1）.resize（1,3）.interior.colorindex = 15，则返回False ...不知道为什么...

Answer 1

Cell interiors can have the same ColorIndex but still have different Color . Maybe this is your problem?

Range("A1").Resize(1, 3).Interior.ColorIndex will only return 15 if all three cells have the same ColorIndex and Color . If Color differs, then it will return Null , even if ColorIndex is the same.

Excel workbooks have a predefined palette of 56 colors. Each of these is associated with a color index between 1 and 56 (0 means no color). (You can edit a workbook's color palette to change what color each index refers to.)

If you assign to a cell interior a Color that is not part of the palette, and then ask what ColorIndex it corresponds to, then the index will snap to that of the closest color in the palette (smallest RGB distance, I think). This is why two somewhat different Color s can return the same ColorIndex .
