Does this make sense to anyone?
From a design perspective isn’t it normal to puck an icon set which has drawn these icons in a specific style. Individually they follow diffent, shape/colour rules so look messy.
It depends what you’re using them for, but it’s pretty common to use the original icons of other services/companies if you’re using them on your website rather than a stylized version.
In my experience, anyways, that’s more common than using a stylized version of a 3rd party logo - and that’s not to mention potential legal issues with using an altered version of a 3rd party’s icon.
Brand guidelines almost always state not to stylise the logo, so this would be the correct way of doing things.
I don’t know what you mean
There are icon sets that have e.g. a twitter icon in a slightly different style that looks a bit more like the rest of the icons. So a bit rounder, or with thicker lines, or with a pink shadow or whatever.
Okay
You can still style them in the color you want and show their respective brand colors on hover.
