hmm...never looked for the gauge colors, but my guess is that they're not in an rco, probably sprx or even self.
Are named "progress", the common ones, in old firmwares, was located inside explore_plugin_full.rco
tex_default_progress_base.gim
tex_default_progress_base_shadow.gim
tex_default_progress_slider.gim
But also in other rco files:
sacd_plugin.rco
system_plugin.rco
videoeditor_plugin.rco
videoplayer_plugin.rco
And yesterday i was taking a look at some rco from 4.85 (i dont remeber which one), and if i remember right i found more variants of it... so i think they have changed his location (or his names)
don't know what bar you're referring to, but the bars/lines on the screen are called separators I believe. upper and lower or top and bottom (can't recall which).
This ones are the (very thin) horizontal bars at top and bottom of some screens. Doesnt have an strict codename, sometimes are called "separators" and sometimes "separation" (and eventually we are going to find other name variants, like separatists, and separouter, lol)
As example, inside system_config_plugin.rco 4.85
<Plane name="plane_wizard_separation_upper">
<Plane name="plane_wizard_separation_lower">
<Plane name="plane_power_off_date_time_config_separation_upper">
<Plane name="plane_power_off_date_time_config_separation_lower">
<Plane name="plane_sysconf_filer_separation_upper">
<Plane name="plane_sysconf_filer_separation_lower">
<Plane name="separator_upper">
<Plane name="separator_lower">
And i think there are tenths of them inside other rco files (so could be a pita to find all them)
Also... something very interesting related with this separators.... is are always located inside an object named "wizard"
That "wizard" is the screen itself... as something conceptual, everytime you see one of that screens with a thin horizontal bar at top and other at bottom is because you are inside one of that "wizards"
