welcome to the forum Styx!

mouse.ini has color settings for all the cursors & reticles, also other interesting effects like spin that you can apply to other cursors.you can fade the color with alpha channels which are in the color ranges around 55.if you want to see some specific code you can download my no-HUD screencapture mod(thats its name) & look at mouse.ini and hud.ini,i've turned all the flight cursors invisible and eliminated the targeted reticle that you see expand around a selected object

Thanks. It has helped a lot. However there is one thing that is still unclear. How is the target cross (the red plus sign we shoot at) or the shield, health bars on target ships edited ?
