I'm making my first hud from scratch, and I've got these team coloured bars:

I want to change their opacity, but I'm not sure how. Here's the code for the health's bar:
"TeamIndicatorLeft"
{
"ControlName" "CTFImagePanel"
"fieldName" "TeamIndicatorLeft"
"xpos" "100"//0
"ypos" "350"
"zpos" "-100"
"wide" "250"//350
"tall" "60"
"autoResize" "0"
"pinCorner" "0"
"visible" "1"
"enabled" "1"
"image" "../hud/color_panel_brown"
"scaleImage" "1"
"teambg_1" "../hud/color_panel_brown"
"teambg_2" "../hud/color_panel_red"
"teambg_3" "../hud/color_panel_blu"
"src_corner_height" "40" // pixels inside the image
"src_corner_width" "40"
"draw_corner_width" "0" // screen size of the corners ( and sides ), proportional
"draw_corner_height" "0"
}
