我无法使用获取标题颜色的渐变色Xbaposter，当我使用 Xelatex 进行编译时，只给出简单的颜色，问题在两行中headerColorOne=black,，并且headerColorTwo=lightblue,带有颜色的定义\definecolor{lightblue}{rgb}{0.145,0.6666,1}。 .cls 文件可以从以下位置下载加拿大运输安全局。MWE 中标记有问题的 3 行：

更新
自 3.1.3 版本起，tikz现在支持 CMYK 阴影，因此不再需要加载pgf-cmykshadings。（但该错误尚未修复。）
pgfpages包 (由 加载[xe]baposter)、pgfsys-dvipdfmx驱动程序 (由) 和着色器之间存在冲突xelatex。我不知道具体发生了什么，但最终结果是着色器无法与xelatex。我已在 提交了一份错误报告https://github.com/pgf-tikz/pgf/issues/520。
无论如何，如果我们指定我们想要驱动程序，它确实有效pgfsys-dvipdfm，尽管这可能会有其他副作用。
此外，在您的海报设置中，您已headershade=plain完全禁用标题中的阴影。因此，您需要删除此选项。
正如评论中提到的，如果您要使用阴影，(xe)baposter建议使用软件包pgf-cmykshadings，这样您就不会遇到意外的颜色不匹配。在您的特定示例中，这种情况不会发生，但总是有可能发生。这是因为所有纯色都将以 CMYK 输出，但所有渐变都将以 RGB 输出。无论您如何在文档中定义颜色，都会发生这种情况。如果您在渐变中使用一种颜色，而您在其他地方也将其用作纯色，它们看起来会有所不同。鉴于此，我lightblue在 CMYK 中重新定义了您的颜色，因此它在屏幕上看起来与您的 RGB 定义大致相同。
所有这些事情都可以通过将其放在您的之前来完成\documentclass：
\def\pgfsysdriver{pgfsys-dvipdfm.def}
\RequirePackage[cmyk]{xcolor}
\RequirePackage{pgf-cmykshadings}
顺便说一句，如果你能将示例做得更简洁，那么将来就会更容易。这有助于我们更快地缩小问题范围。
