Im new to understanding Matlab and i have a two part question.
1. Is this colorbar automatic colors? As in Matlab picks its default colours? Because i do not choose colours anyhere, and just type these two commands in and i get a blue/yellow/green colour on the figure. What does cb stand for?
colorbar;
cb = colorbar;
2. Is there a way to create a manual colour bar using these colours? #0192bf, #41abce, #ffff00, #ffff41, #ffff7f. Im making a contour plot using contourf

"Is this colorbar automatic colors?"
The colorbar just displays the bar which shows the color scale of the figure.
"As in Matlab picks its default colours?"
Yes.
"What does cb stand for?"
cb is the handle to the colorbar object.
"Is there a way to create a manual colour bar using these colours? #0192bf, #41abce, #ffff00, #ffff41, #ffff7f. Im making a contour plot using contourf "
There are loads of other questions on this forum with examples of making custom colormaps for a figure. Go through them.

"Is this colorbar automatic colors? As in Matlab picks its default colours?"
Yes. The default colormap is described here:
"What does cb stand for?"
I guess that CB stands for "ColorBar". But the name of that variable is much less important than what it is: a COLORBAR object:
"Is there a way to create a manual colour bar using these colours? #0192bf, #41abce, #ffff00, #ffff41, #ffff7f."
S = ['#0192bf'; '#41abce'; '#ffff00'; '#ffff41'; '#ffff7f'];
M = sscanf(S.','#%2x%2x%2x',[3,Inf]).' ./ 255;
Z = peaks;
contourf(Z)
colormap(M)
colorbar()
