提问by James Raitsev
While it is of course possible to use BaseColor, by default, it offers very limited choices.

Lots of options.
很多选择。
BaseColor color = new BaseColor(red, green, blue); // or red, green, blue, alpha
CYMKColor cmyk = new CMYKColor(cyan, yellow, magenta, black); // no alpha
GrayColor gray = new GrayColor(someFloatBetweenZeroAndOneInclusive); // no alpha
There's also pattern colors and shading colors, but those are Much Less Simple.
还有图案颜色和底纹颜色，但这些都不那么简单。

It seems one can create a new BaseColorfrom WebColor as:
似乎可以BaseColor从 WebColor创建一个新的：
BaseColor myColor = WebColors.GetRGBColor("#A00000");
Which then can be added as a background as:
然后可以将其添加为背景：
cell.setBackgroundColor(myColor);

One more solution is:
另一种解决方案是：
public static String mColor = "#aa8cc5";
int aa = Integer.parseInt(mColor,16); // base 16
int colorArr = Color.rgb(Color.red(aa),Color.green(aa),Color.blue(aa));
cell1.setBackgroundColor(new BaseColor(colorArr));

Try this:cell.setBackgroundColor(new BaseColor(226, 226, 226));
or:cell.setBackgroundColor(WebColors.getRGBColor("#E2E2E2"));deprecated
试试这个：cell.setBackgroundColor(new BaseColor(226, 226, 226));
或：cell.setBackgroundColor(WebColors.getRGBColor("#E2E2E2"));已弃用
