While I'm not a competitive player, I've loved using this HUD and made a few modifications, but I'm kinda stuck on this next bit. I've been fiddling around with the TargetID.res trying to get a team-coloured something into the hover (similarly to how the Spectator on teams shows the coloured bar.)

So far, with a few looks at the stock targetID.res, I've done this

	"TargetIDBG"
	{
		"ControlName"		"CTFImagePanel"
		"fieldName"		"TargetIDBG"
		"xpos"			"0"
		"ypos"			"8"
		"zpos"			"-40"
		"wide"			"252"
		"tall"	 		"20"
		"autoResize"		"0"
		"pinCorner"		"0"
		"visible"		"1"
		"enabled"		"1"
		"image"			"../hud/color_panel_brown"
		"scaleImage"		"1"
		"teambg_1"		"../hud/color_panel_brown"
		"teambg_2"		"../hud/objectives_timepanel_red_bg"
		"teambg_2_lodef"	"../hud/objectives_timepanel_red_bg"
		"teambg_3"		"../hud/objectives_timepanel_blue_bg"
		"teambg_3_lodef"	"../hud/objectives_timepanel_blue_bg"

		"src_corner_height"		"23"				// pixels inside the image
		"src_corner_width"		"23"

		"draw_corner_width"		"0"				// screen size of the corners ( and sides ), proportional
		"draw_corner_height" 	"0"	
	}

Basically it makes a team background colour behind the main TargetID info but there's a little bit too much colour extending below the main panel. I have no idea if I'm even calling the appropriate teambg file (and I don't know where to find it exactly.) The width/height[wide/tall] in the code doesn't seem to change much/anything, so I'm not sure if I can really do something about it.

As I sorta implied, I mostly just casually/pub play. However, when I'm doing some Spy, sometimes the lack of team colours can be a pain on maps where players might hide in shadows or be at a great distance.
