Is there a difference between the gray and the red / blue / gray Nintendo Switch?

On the subject of Nintendo Switch, mur was told that the gray switch has bigger buttons than the colorful one. Is that correct? And / or are there other changes?

Personally, I doubt that, but would like to ask users

Is only a color difference

Except for the colors, there's no difference

That does not matter, there's also still the possibility to order a "skin" for you switch, costs 15 euro and can choose the design itself, should you not like the color then
