[vtkusers] Set point color knowing its value

[B. C.]

Hi everyone.
I have a polydata. I computed its maximum curvatures and stored the values in an array.
Now, i want to do this: 
for each value in the array, if it's <0 set its color to 'red', else to 'black'
I did this:
vtkIdType nPoints = myArray->GetNumberOfComponents();
double curveValue;
for (vtkIdType i=1; i<=nPoints; i++)
{
  curveValue = myArray->GetValue(i);
  if (curveValue<0) 
   //Set the color to 'red'
  else 
   //Set the color to 'blue'
 }
 
Can someone help me to fichish the missing code?
Thank you for your help
