There is a simple way to highlight all fields in Word. Go to Word options, advanced, then under Show document content, choose "always" in the "field shading" option. A shame it's in grey and not yellow, but very useful all the same.

Use the below C# code to highlight all MathType equation in yellow color. Before using the this code add using Word = Microsoft.Office.Interop.Word; in namespace declaration in your class file.

public bool FindAndHighlightMathtypeEquation(ref Word.Range myRange)
    {
        try
        {
            int inlineShapesCount = myRange.InlineShapes.Count;
            if (inlineShapesCount > 0)
            {
                for (int i = 1; i <= inlineShapesCount; i++)
                {
                    Word.InlineShape currentShape = myRange.InlineShapes[i];
                    Word.Range currentShapeRange = currentShape.Range;
                    Word.WdInlineShapeType typeOfCurrentShape = currentShape.Type;

                    if (typeOfCurrentShape != Word.WdInlineShapeType.wdInlineShapeEmbeddedOLEObject)
                    {
                        continue;
                    }

                    if (!currentShape.Field.Code.Text.Trim().ToLower().Contains("equation"))
                    {
                        continue;
                    }

                    currentShapeRange.Select();
                    currentShapeRange.Application.Selection.Range.HighlightColorIndex = Word.WdColorIndex.wdYellow;
                }
            }

            MessageBox.Show("Process Completed");

        }
        catch (Exception)
        {
            throw;
        }
        return true;
    }
