I only try to match them if it's the same company, ie all red Lelos, otherwise they'd be the wrong shade.
I tried to match all my JeJoue's in purple but the different toys have slightly different silicone so they don't match >.< I'm glad I ended up going with a black MiMi instead of a purple.

I buy whichever colour I like best. I love, love, love purple, but not all companies offer their toys in purple. Sometimes I match within the same company, if I can for all the toys. Other times I pick whichever shade looks the nicest on the toys. I have turned my nose up at purple toys because there's another colour that just happens to look nicer than that shade of purple. Like with the We Vibe. The purple colour is nice, but I just love that cherry red, so that's what I'm getting. Other than purple, I tend to pick blue, red, or greyscale. I tend to stay away from white and pink.

I go for variety.

By the time I realized it, I already had a number of purple toys, and one or two pink. Now, I tend to go with it if purple is available but I won't rule anything out just because of color, of course!

No, not so far.

I do the opposite, I go out of my way to get as random of colors as I can.

My toybox is BEAUTIFULLY color-coordinated. Lots of black and white, with splashes of deep colors mixed in (deep purples, rich blues).

I loathe pastels, so I avoid them when I can.

We really just do it on a case by case basis

I don't really care too much about the colors. i just pick the a color I like for a particular toy.

I don't really care if my toys match. However, I tend to go for certain colors. Currently half of my toys just happen to be purple, which I didn't really try to go for.

Black or deep purple is what I normally buy.

it just kind of happened

Its nice having different colors to spice it up.
