Pretty much every single colour in existence and might as well make up a few new ones too.
Oh also, how about to match the fabrics in the Thimble shop you could even do multi-colours like and
But mainly we need orange, because of Halloween, we have frighteningly(hehe) few orangy things for that holiday.
Burgundy, black, deep red/ruby, dark brown, silver, royal purple, medium/dark green, and grey have my vote! I don't think we have those yet in newer flats, but I'm also forgetful of stuff like that.
Shade ideas: Burgundy - Deep red/ruby - Medium/Dark Green - Think Slytherin colors. This CW background has tons of colors in it that would work nicely! Black - A dark shade, like the Simplistic Black Flats, but in a design similar to the basic flats.
Would love to see some in a dark/royal purple colour! ^.^

ALL. THE. NEON. COLORS.

I always like seeing blues that match stuff like these: etc.
Speaking of the bell skirt, shades that match each of them would be nice, since some are a tad unusual:
Then some basic colors, like red, orange, blue, black, etc. to match the usual shade for those.
Darker versions, like navy, maroon, burgundy, etc.
Royal colors, like royal blue, deep purple, etc.
Off shades, like: etc.
I definitely agree with regarding the bell skirts, I'd love to see shoe colours that match those!
Also I think colours like these would be really good c:
A colour like these flats would be amazing, these flats are too pointy for my liking or a darker brown similar to
Also these are nice:
and the two shades of green in this dress or a green similar to in this
OK PLEASE STOP ME NOW SERIOUSLY but these colours would be a good example as well
I love your idea of the neon colors! so many items are being released in brights and it sucks never having any bright shoes
Different types of gray (some a bit coloured too)!
Stuff to match the grays in...
more than one brown shoe, there is such a range! vs. using these two for example
-yes to oxblood or burgundy -yes to that zombie dress green -also yes to teal. we need a good standard teal
omg I wasn't even expecting to post on this thread but when I saw your idea using the cake frosting colors...two words:
THIS. TEAL.
I NEED THIS TEAL IN MY LIFE ;-;

There are already so many existing colours on site cough those frosting cough that would be perfect for the basic flats ;_______;
I hope some of them are implemented!
PIIIIIIIIINK .... PIIIIIIIIIIIIIIIIIIINK
... That is all.
Slams fist on table YAS
Otherwise: Teal, magenta, red and grey.
I was going to say the same thing! Also the same as the neon skinny jeans:

The green and the orange are pretty much duplicate colors, but you get the idea. :D So excited for this! <3
Another thought kind of thing - you know how in the Flat Heels line there are a few ranges of each color?
Like the that is sporting. There are a couple/few different shades/tones of each color in that lines, and I know those get a ton of use because it makes them so versatile. So maybe just along those lines, a wide range of the basic/most common popular colors, and different variations of each color.
I have my problems matching most of the green items on site with shoes. The green flats are more mint in color and other shoes are too dark, I'd love to see more really green tones and in-between shades. I especially think of shades like in the Cece Kat Green Shoes as well as a tad darker than these.
That's a shame because a really white white would have been nice ^_^;
I'm also with on liking the idea of some more browns
Oh Im so going to have to make a little list. A few of my fav items are so hard to match to! I hate always giving up and using black. When I wake Ill hopefully remember to get to this!
God yes more browns! Especially a dark brown that isn't so dark it looks black.
I'd love love love to see shoes that match the masquerade corset dresses/lacy cropped jackets from several years ago.
Also, and more than shoes would be great ;), nothing really matches the Android Assassin dress and sleeves (they don't really even match each other very well) but they are such nice colors.
