This is what it looks like on mobile. Not very easy to see especially zoomed out.
Agreed, a bit too subtle even on my laptop. Here are some more options:
The image in
@Miyaru's post the same color as Option 1 below but 60% transparent.
Option 1: Here is the image with no transparency and black text
Option 2: Here is the banner with pure red, no transparency, and pure white text.
Option 3: Here is Option 2 with the red banner at 60% translucent
Option 4: Green Banner, black text
I can go on but I guess the first question is how subtle or hard to miss do we want the indicator to be?
My unscientific opinion is that there are more avatars with blacks and blues than other colors so those banner colors would stand out less. Maximum contrast is pure black and white, especially with color blindness.
Keep in mind, I'm a very simple guy. I can match a color if you point me to it but names like mauve, periwinkle, and puce won't register.
