Find another issue with the font of annotation of colorbars:

 ![41060d8a6b631a4c15a7f959e8e2ac81c7b3846d_2_1380x478](https://canada1.discourse-cdn.com/flex047/uploads/gmt/original/2X/d/de6cf2918fb9a7cbac23988dfa566967a7e73ef5.jpeg)  
I tried to set the font larger but it did not work (in GMT6.5):

```auto
gmt set FONT 12,Times-Roman
gmt set MAP_ANNOT_OBLIQUE anywhere

gmt begin gravity png
gmt grdimage @earth_faa_01m -JOb168/51/172/32.5/14c -R-500/2300/-400/400+uk -BeNsW -Bxa5f1 -Bya5f1
gmt colorbar -C -Dx14.2c/2c+jML+w3c/0.2c+mc -Ba100f50 -By+lmGal
gmt colorbar -C -Dx7c/-0.2c+jTC+w6c/0.2c+mc+h -Ba100f50 -By+lmGal
gmt end show

```

It works well in GMT 6.4.

Yes, things have changed a bit in 6.5. See [here why](https://github.com/GenericMappingTools/gmt/pull/6802). Basically the modern mode theme scales down the fonts depending on the colorbar length. So, the `FONT` is still working but is scaled down. To set a fixed size font use the online `--FONT=...` construct in colorbar commands.
