Snippets Interior Color (Tint & Shade)

Applies a theme color to a range and then alters the "TintAndShade" value to make the theme color lighter or darker.

IWorkbook workbook = Factory.GetWorkbook();
IWorksheet worksheet = workbook.ActiveWorksheet;
IRange cells = worksheet.Cells;
cells["A1:F10"].Interior.ThemeColor = ColorSchemeIndex.Accent1;
for (int row = 0; row < 10; row++)
{
  double val = -0.5 + (2.0 / 15) * row;
  cells[row, 0].EntireRow.Interior.TintAndShade = val;
}
