My monitor distinguishes between colors very nicely (woot! Same goes for my phone), but for those two colors, it's hard to see the difference at a first glance.
Yes, it's easy to see the difference when they're out side by side like the way DD put them, and yeah, you can just look at the text instead of the colors... but
when you're just glancing over them and the text becomes blurred/inconsequential (and they're already pretty similar anyway; the word "very" doesn't make much of a difference when I'm skimming over things quickly), it's very hard to distinguish them at a glance. I have to actually focus/concentrate in order to tell the difference between the text and the date (and, usually, the name as well; yes, I do like giving my pets names when I adopt them, and it takes too long to go and erase the names of my trade pets) when I'm skimming over them (which is one of the reasons I'm using the color-coded bars instead of the text...), so no, I cannot just look at the text.
When rarity changes come out, I can easily find the yellows in a sea of green or the cherries in a group or oranges or the oranges hidden in the yellows. I can even distinguish the teals in a group of blues because the blue for OMGSC is rather deep. But it's difficult to find the greens in a sea of teal; they're too similar.
It's not just a problem when sorting my groups, either! I've had to back up and rethink my decision on several trades involving commons and very commons. (It doesn't seem like a big deal until you realize that someone who wants your 2011 common is actually offering a 2012 very common, not a 2012 common. At least, that's a big deal to me since it seems like the gap gets a little dangerous. And since I usually don't want to edit for fear of what the other person might say...)
I'd been thinking it was just me with the problem ever since the labels came out; I had been terrified of bringing it up since I wasn't sure that anyone else would support this. Glad to see I'm not the only one now.
Also,
the stars' places do not mean much when you're just glancing at things; all that matters is which side it's on or if it's on the middle.
On phone with limited time; my apologies for any typos I didn't catch or awkward phrasing that I didn't have a chance to reword. Reworded a few things now. Should be okay now; let me know if there's something I should rephrase. I don't really like being misunderstood, so I want to prevent that. ^_^
edit:
my second long post about this is here. It's getting buried -coughshamelessselfpromotioncough-
