U've neglected to pay attention to the color alpha value in the hex code for the color ur using.

e.g.

0xRRGGBBAA

will give a nice kinda semi see through white

0xRRGGBBFF

will give a very vibrant white

and,

0xRRGGBB00

will give a completely invisible white.

You can also embed colors into the text in order to change it half way through,

e.g.

CreatePlayer3DTextLabel(playerid,"{0000FF}Fuel Station: {FF3300}Large Vehicle Type", 0xFFFFFFFF ,0,0,0,30.0,INVALID_PLAYER_ID,vehicleid,0);
