Is there an easy way to set the background color of rows in the changelist view?

I know that I could write my own page to do this, instead of over-relying on the admin; but before I do that, I'd like to be sure there's no easy way to get the admin to do this.
If you look at the usual "poll" app from the tutorial:

I'd like the row whose question text is "blue" to be colored blue, and the row whose text is "red" to be colored red. In general, I'd like to write a bit of code somewhere that

• gets the value of the question column
• uses that as the key to a table, to get (say) a hex code for color
• somehow applies that color to the row

Is this easily doable?

This kinda does it for just that one column: ```py
@admin.display(description="Color")
def colored_question(self):
return format_html(
'<span style="background-color: {};"><tt>....</tt></span>{}',
self.question.lower().replace(" ", ""),
self.question,
)

Maybe you could make colored_question output e.g. <span class="blue">... and then add some custom CSS with .changelist tr:has(span.blue) ... ? Just throwing some ideas out there and hoping it helps somewhat.

If a simple CSS solution is not sufficient I think I'd write some JavaScript. Customizing the ChangeList with some JS code is relatively straightforward, but it also tends to break between releases when the HTML is changed a lot. I mostly only use this technique in OSS projects where I have unittests which verify that the behaviors still work.

I don't think using class is any better than style, because (I assume) in both cases the effect is confined to just one column.

In case it's not clear, I only have a dim understanding of CSS 🙂

@static raft The advantage of using class would be that you can use :has to target tr elements which contain elements having the particular class. It sounds like that's a bit too advanced or specific. If you're happy with only coloring a cell and not the row: Do what you're doing currently. If you need to color the whole row, write some JavaScript which lifts the style from the cell to the row, or maybe, maybe use the :has trick I mentioned. But yeah, I'd recommend either the simple version of only coloring the cell or the hacky version of writing JavaScript to apply styles to the row.
