Hi @Anonymous
Once you have the text object
TextObj
This will have some properties, look at debug, you can change color, font, and so on, add special char.
If you want to use true color for example it's more or less different see below code:
Dim color As AcadAcCmColor
Dim sVer As String = Left(acadDoc.GetVariable("ACADVER"), 2)
Set color = AcadApplication.GetInterfaceObject("AutoCAD.AcCmColor." & sVer)
'Above automatic Get Cad Version, below manual.
'Set color = AcadApplication.GetInterfaceObject("AutoCAD.AcCmColor.20")
'For Acad2015, use AutoCAD.AcCmColor.20
'For Acad2016/17, use AutoCAD.AcCmColor.21
'For Acad2018, use AutoCAd.AcCmColor.22
'For Acad2019, use AutoCAD.AcCmColor.23
Call color.SetRGB(80, 100, 244) ' Set RGB colors as you want
TextObj.TrueColor = color
You will find a lot of literature on forum about text properties.
