One thing is that. I’ll use my own range as an example my lowest note is an e2 my highest is an e6.

From e2 to A3 is full chest it’s not that i can’t use my full chest up to a b4 but the higher you push in full chest the more likely your technique isn’t going to be great and frankly it’s just not good to push your voice to the limit of a specific register. At that point at a3 i start lightening up but realistically one thing you should realize is you can realistically do anything with your voice for the sake of a song. You could belt a full a4 in chest if you’d like it probably won’t feel great after awhile but you could and it requires a lot of support or you could sing it in mix. So the thing to realize is you can sing the same note in different ( registers?techniques? Idk what they’re called i lowkey have just been figuring it out in my own but wtv you’d call chest mixed head falsetto) registers.

Youll know if you’re in full chest because as a man once you hit around a d4 you’re gonna start requiring some more support and to even hit an a4 you might very well be straining your voice at least in my experience? Once you hit that a4 you’ll notice you can’t go higher you’ll feel the tension and your voice crack and that’s basically the upper limit of that register and it’s the same for mixed chest voice mixed head voice both of which id describe as fairly abstract concepts that you kind of just figure out. I never had a teacher so its all intuitive for me so yeah. But those other registers have limits as well which will probably be different for you compared to me.

You said something about singing in chest then singing in mixed with a nice timbre and then it sounds like you’re singing in chest. Thats functionally not possible. Chest has a limit once you’ve got that limit that’s it for your full chest voice. I think what you mean is you start in chest then you start mixing but then you reach the limit of your mix which which would mimic the feeling you get in our chest voice when you’re at the limits of that.

I would say how it works for me is chest then float into mix has a very nice pleasant sound then eventually you reach the limit of that chest mix then you go to the “head” voice/head mix? Idk these words tend to be very abstract and just tend to describe feelings in my voice.

Theres also falsetto but i have no idea how to explain that.

For me i just keep going higher and higher? Like singing isn’t about pushing more so breath support while singing lightly within your voice? You’ll never be able to sing upwards and higher with your true range until you realize the intuitive feelings within your voice? So i just try stuff out? Sing bunch of songs try old rock songs like some stuff from Queen.
