I've been paying attention to new suggestions lately and haven't seen anything related to this but do point it out if I missed something.

When a pet becomes unconscious, their image in the stables [and maybe in the hatchery, though I've never seen it myself] becomes greyed out.
This is a nice feature for telling others what the pets status is [I've also noticed that certain mutations do keep their color- neat little feature, admins! Nixi Spirit flames and Ryori tails!] but recently, I've found threads by users advertising pets for sale and they haven't fed their pets. The first and biggest thing that I let catch my eye when I browse for-sale pets is color, followed by visible traits. Because of this, I have to go by traits alone and then open pets up in a new tab so that I can see their colors. This can get pretty messy if the person has a massive amount of grey pets for sale.

For cases like these, I wouldn't mind having some kind of toggle option to turn off the unconscious Grey image.

Of course, this would only affect the image of the pet and would have nothing to do with the actual state of it. It would still be unconscious and would need to be fed before any fighting or breeding took place, but the colors could be viewed without going to the pet's profile.

I definitely agree with this.

Thank you for making this thread! It's something that's been on my mind lately too - I definitely would love to be able to toggle the grey-out for viewing other people's stables but also my own.

I'd really like this, <w> considering Krin did say it could be made toggleable back in the news thread originally. ;)
