推荐答案
了解如何创建颜色的最佳方法是检查'颜色'类，您会看到它具有几个子类:
The best way to find out how to create colors, is to check the API docs. When you go to the page that describes the 'Color' class, you see that it has several subclasses:
- DeviceGray
- DeviceRgb
- DeviceCmyk
- ...
您似乎要创建RGB颜色，因此需要DeviceRgb:
It seems that you want to create an RGB color, hence you need DeviceRgb:
Color headerBg = new DeviceRgb(0xA6, 0xCB, 0x0B);
Color lineColor = new DeviceRgb(0xCC, 0xCC, 0xCC);
您可以使用color对象设置边框，背景等的颜色...
You can use the color object to set the color of borders, backgrounds, etc...
