Highlight color different in Finder?

I've also noticed that in several applications, such as Firefox and Thunderbird, it uses light olive green to highlight some things (eg. lists of of emails) and yellow to highlight other things (eg. text of emails), when it used to use yellow consistently.

Crap, this forum just deleted what I just wrote. I guess I have to cut and paste everything to save it. Now, I have to re-write everything. This is very annoying.

Whereas I appreciate your reply, setting the Accent color makes no difference. Did you actually try it? Setting the Accent color as "Yellow" displays as orange. "Yellow" should look yellow. So something is definitely wrong. I'm not a professional visual artist, but I at least have a kindergarten understanding how colors are named, and can manage to buy the right fruits at the supermarket. There doesn't seem to be anything wrong with the color settings on my monitors, as pictures, video, and graphics, as all appear as they should. Yet, the "Yellow" Accent looks like the same hue as "Orange" only a bit lighter. That's not right.

Although I prefer grey, to the default blue Accent color, no matter what color I choose For Accent, the Highlight still shows as olive green in the Finder and other applications as described above.

Also, there seems to be something very screwy with with this forum's software. Not only did I lose a post, I couldn't seem to add more text after the last sentence of my last post.

Just to clarify, changing the Accent color to pink, red, or whatever, still results in the highlighting in the finder as olive green.

Further, there doesn't seem to be a way to adjust the Accent colors, because unlike the Highlight colors there is no way to select "other".

Sorry, for the additional posts. That was in my original post that got eaten.

Let's reiterate for clarity:

1. The Highlight color for "Yellow" doesn't even look yellow in System Preferences/General. It looks light orange, and results in light orange.

2. The Accent for "Yellow" doesn't even look yellow in System Preferences/General. The button looks orange, and results in orange.

3. No matter what color is selected for Highlight, it's a different color in the Finder and in parts of various applications. For example, if "Pink" is selected, highlighting in text edit is pink, but a dark reddish purple in the Finder. So perhaps, it's the same hue, but darker.

4. However, if you select "Other" under "Highlight color" to get yellow, it's olive green in the Finder and in parts of various applications. So something is definitely wrong, as green is not even a darker shade of yellow.

5. There doesn't seem to seem to be a way to set "Accent color" to yellow because there is no option for "Other". So they can't be set the same.

6. Even if that were possible, "Accent color" seems to have no affect on "Highlight color". Nor is there any logical reason why it should — they are two different things.

It's not a matter of getting the Highlight colors to match exactly. In Sierra, I had it set to Yellow, and it was yellow in both Text Edit and the Finder. Now, they are completely different colors. So something is broken.

That Apple doesn't care that it's colored wrong is a bizarre defense.

Regardless, something as basic, common, and long-standing, as yellow highlighting should work. It's been a standard feature of operating systems since color monitors became popular.

Oh, it's definitely broken. It's also "changed" — changed so it doesn't work.

I find it hard to believe that no one noticed the buttons labeled "Yellow" weren't colored yellow.

FWIW, I shared my thoughts with Apple.

Still, no idea why they would set "Yellow" — for both Accent and Highlight — to lighter shade of "Orange" when simply could have made "Yellow" yellow.
