How to adjust the distance between the label and the colorbar in pygmt

Hello everyone, when using pygmt to draw a colorbar, the vertical distance between the label and the colorbar is too small. I would like to increase the distance between them, but I haven’t found a way to do it. Could someone please help me with this? Thank you very much!
colorbar

Here is my code:

fig.colorbar(
    cmap=True, 
    position="JMR+w5c/0.5c+o0.7c/0c", 
    frame=[f"a295"]
 )
fig.colorbar(
    cmap=True, 
    position="JMR+w5c/0.5c+o0.7c/0c", 
    frame=[f"a255", "y+lLST(K)"]
)

For those cases you should consult the gmt.conf manual page. I think what you want is the MAP_LABEL_OFFSET

@Joaquim I previously tried setting MAP_LABEL_OFFSET through gmt.conf, but it didn’t work.

OK, the parameter is MAP_ANNOT_OFFSET, but an issue is that we don’t have a mean to specify different offsets for x and y axes.

@Joaquim Thank you for your answer!
