kivymd主调色板的自定义颜色

Question

是否有任何方法可以为kivymd主调色板以十六进制的形式应用自定义颜色?

像这样

self.theme_cls.primary_palette=hex('#171717')

我认为只能通过肮脏的黑客。

from kivymd.color_definitions import palette, text_colors, light_colors
enter code here`palette.append("Black")
text_colors["Black"] = {
"50": "000000",
"100": "000000",
"200": "000000",
"300": "000000",
"400": "000000",
"500": "000000",
"600": "000000",
"700": "000000",
"800": "000000",
"900": "000000",
"A100": "000000",
"A200": "000000",
"A400": "000000",
"A700": "000000",
}
light_colors["Black"] = {}

这个<<p> strong> 第一次导入Kivy或kivymd，否则会引发KeyError。

然后你还需要在自定义字典中定义你的自定义颜色。

custom_colors = {
"Black": text_colors["Black"] # you can also repeat all values and adjust
}

最后我们需要设置新的自定义颜色(最好是在构建中)

class MyApp(MDApp):
def build(self):
self.theme_cls.colors.update(custom_colors)
return RootWidget()

现在你可以使用你的自定义颜色。

免责声明;这看起来很粗糙，我不建议在没有测试的情况下在生产中使用它。也可能有更好的方法，但我找不到任何记录。最好的办法可能是覆盖一个已经定义的颜色(比如"青色")，并设置你喜欢的值。可能会导致颜色冲突。
