If I have an instance that is just written text how do i dynamically change the text color when the mouse goes over the text?

Hello,

Is the instance a LayerData instance?

looks like this
<MTSInstance Name="Text">
<LayerData Name="Callout" Text="Enter text here" TextColor="0 0 0" Font="Arial" Language="English" TextSize="14" DstPin="0 0" SrcPin="0 0" SrcPinRel="0" DstPinRel="0" DstPinFlag="0" AlwaysVisible="1" HitTestAlpha="0" />
</MTSInstance>

Do this:

<MTSInteractor Name="myinteractor" >
<Target Name="MTSInstance.Text" />
<MTSHandle Event="MouseEnter" Action="MTSAssignProperty" Target="Callout.tclr" Value="0.32 1 0.655" />
</MTSInteractor>
