Appreciate the follow up. This full sample code will demonstrate the issue.
If you only draw the Tool a single time (controlled by a persistent), the text is white.
If drawn a second time, it will turn from white to green.



SCSFExport scsf_DrawingTest(SCStudyInterfaceRef sc)
{
int& r_MaxDrawCount = sc.GetPersistentIntFast(0);

if (sc.SetDefaults)
{
return;
}

if (sc.Index == 0)
{
r_MaxDrawCount = 0;
}

// set this to 2, text will be green. set to 1 and it is white.
constexpr int kMaxCount = 1;

if (r_MaxDrawCount < kMaxCount)
{
++r_MaxDrawCount;

const int beginIndex = sc.ArraySize - 10;

s_UseTool newRay;
newRay.ChartNumber = sc.ChartNumber;
newRay.DrawingType = DRAWING_HORIZONTAL_RAY;
newRay.LineNumber = 1;
newRay.AddMethod = UTAM_ADD_OR_ADJUST;
newRay.Region = 0;
newRay.BeginIndex = beginIndex;
newRay.BeginValue = sc.Close[beginIndex];
newRay.Color = RGB(255, 0, 0);
newRay.LineWidth = 1;
newRay.Text = "TextColor probe";
newRay.TextColor = RGB(0, 255, 0);
newRay.FontSize = 12;
newRay.TransparentLabelBackground = 1;

sc.UseTool(newRay);
}
}
