有没有什么方法可以使用 biblatex 来获取某些 bib-keys / bib-entries 的引用，并且只为它们获取不同的颜色？
在下面的 MWE 中，我制作了一个自定义命令（灵感来自这个答案) 以显示不同颜色的引文。然而，我正在寻找一种让 biblatex/biber自动为引用某些条目的引文添加颜色，并且只为它们添加颜色，无需使用任何自定义命令。在文本中，将使用相同的命令（例如\parencite），但对于指定的条目（例如articlecoloured），输出将是彩色的；对于其他条目，则不会。
换句话说，使用 MWE 中“无自定义命令”部分中的引用命令，但获得与“使用自定义命令”部分相同的输出。
该示例包括一个具有两个条目的 bib-content，articlenormal和articlecoloured。
我希望能够使用正常的引用命令（\parencite、\citeyear等\textcite），但对于某些 bib-keys（articlecoloured）输出会带颜色；对于所有其他（例如articlenormal）则不会。（在我的工作文档中，我为使用的各种引用命令定制了命令，它们都像在 MWE 中一样带颜色输出。在 MWE 中，我只包含了\parencite。）
是否有可能获得articlecoloured且仅articlecoloured拥有自定义颜色不使用自定义引用命令？
也许要对哪些文件条目进行着色可以基于键列表（即articlecoloured），或者在文件条目中包含相关关键字？
（如果指定要着色的条目在参考书目中也是彩色的，则可以获得加分。）

答案1
cite本质上我们‘只是’需要采用和bibmacros的原始定义textcite并在其中添加一些颜色。
原始定义可以在apa.cbx（ll. 189-261 在 v9.6 中）。
在此示例中，你可以定义要用颜色标记哪些引文
\addtocategory{coloured}{<key_1,key_2,...,key_n>}
因此，如果条目仅在某个文档的上下文中着色而不是其本身着色，则这很有用。

如果条目本身就带有色彩，那么使用keyowrds
只需更换
\ifcategory{coloured}
以上
\ifkeyword{coloured}
并使用
keywords = {coloured},
在.bib文件中。
