Hello, I’m totally new to Blender and was following the tutorial when suddenly the vertices of the selected object became light blue. Any suggestions on what that means and how to turn it off?
thanks in advance!
Welcome to BA!
That’s just the selection colour in theme Deep Grey when you have several objects selected – only the active object is orange, all other selected objects are light blue.
It’ll turn off automatically when you deselect the objects.
You might want to use the default theme (Blender Dark) while you’re as yet unfamiliar with Blender, since just about every recent beginner tutorial I’ve seen uses that, and it’s easier if your screen matches theirs; one less thing to wonder about. In that theme all selected objects are orange, the active one is just a little lighter.

But it wasnt like that at the beginning, and the theme indeed was. I cant operate with those objects that are light blue, i tried to join them or select some vertices and it’s just not working
Are you sure that it’s the only thing that could be is that theme?
Wait! So the problem that appeared was that I was trying to select two objects and join them but it didn’t work because one of the selected objects was becoming blue and two objects didn’t become one. But then I changed the theme as you advised, repeated everything and somehow it joined. How’s that even possible? Thank you very much for helping me with this! Don’t know why and how but I guess its just a beginning

I don’t know what happened there; could be any number of things. One I run into still is that most commands are specific to the area of Blender your mouse is hovering over. Like, CTRL-J to join works in the 3D viewport, but if you’re accidentally hovering over the outliner or the properties, it won’t do anything. Also, to join objects they need to be of the same type; you can’t join a light and a mesh, for example. Sometimes you can accidentally have something selected as the active object (like the camera) that blocks the join without you seeing it.
I pressed so many wrong keys in the beginning, which set things somewhere, often out of sight, and weird things happened. So yeah, it’s a beginner problem when things don’t work as expected, and it will get better with practice because for one you learn the right keys to press, for another, you become familiar with what likely went wrong when something goes weird, and you’ll learn how to fix it.
If this tutorial becomes too frustrating, don’t hesitate to do something simpler first, even if it’s not exactly along the lines of what you want to model long-term. I went from the donut to a simple blocky sheep because I got so frustrated with my messy donut mesh it was no fun anymore and I didn’t really learn efficiently. It’s way easier to learn Blender with simple, low-poly starter objects than with organic forms.
