@Epica3055 This PR changes cell size compared to NET8. Could you please investigate if we can adjust color value here or elsewhere - https://github.com/dotnet/winforms/blob/7c9f958bfd13697dbb1007b6d3bf8c41837790cd/src/System.Windows.Forms/src/System/Windows/Forms/Controls/DataGridView/DataGridViewCell.cs#L3154
