I use this code to setup colours for my interface depending on what theme is set.
public static class LFTheme { const int ThemeClassic = 0; const int ThemeBlue = 1; const int ThemeSilver = 2; const int ThemeBlack = 3; public static int Theme { get; set; } public static Color BackColor { get; set; } public static Color ForeColor { get; set; } public static Color ForeColorLight { get; set; } public static Color ForeColorDark { get; set; } public static Color TextColor { get; set; } public static System.Drawing.Font Font { get; set; } public static Excel.Application ExcelApp { get; set; } public static Double ExcelVersion { get; set; } static LFTheme() { InitLook(); } public static void InitLook() { const string OfficeCommonKey = @"Software\Microsoft\Office\{0:0.0}\Common"; const string OfficeThemeValueName = "Theme"; Theme = 0; BackColor = System.Windows.Forms.Control.DefaultBackColor; ForeColor = System.Drawing.SystemColors.Control; ForeColorLight = System.Drawing.SystemColors.ControlLight; ForeColorDark = System.Drawing.SystemColors.ControlDark; TextColor = System.Drawing.SystemColors.ControlText; Font = System.Windows.Forms.Control.DefaultFont; if (ExcelVersion<12.0) return; using (RegistryKey key = Registry.CurrentUser.OpenSubKey(String.Format(OfficeCommonKey, ExcelVersion), false)) { try { Theme = (int)key.GetValue(OfficeThemeValueName); } catch (Exception ex) { Theme = ThemeClassic; if (ExcelVersion >= 12.0) { Theme = ThemeBlue; } } switch (Theme) { case ThemeBlue: BackColor = Color.FromArgb(255, 213, 228, 242); ForeColor = Color.FromArgb(255, 107, 160, 209); ForeColorLight = Color.FromArgb(255, 185, 210, 234); ForeColorDark = Color.FromArgb(255, 87, 149, 204); TextColor = Color.FromArgb(255, 50, 108, 160); Font = new System.Drawing.Font("Segoe UI", 8F, System.Drawing.FontStyle.Regular, System.Drawing.GraphicsUnit.Point, ((System.Byte)(0))); break; case ThemeSilver: BackColor = Color.FromArgb(255, 232, 236, 243); ForeColor = Color.FromArgb(255, 158, 162, 161); ForeColorLight = Color.FromArgb(255, 200, 206, 205); ForeColorDark = Color.FromArgb(255, 128, 133, 131); TextColor = Color.FromArgb(255, 116, 118, 123); Font = new System.Drawing.Font("Segoe UI", 8F, System.Drawing.FontStyle.Regular, System.Drawing.GraphicsUnit.Point, ((System.Byte)(0))); break; case ThemeBlack: BackColor = Color.FromArgb(255, 83, 83, 83); ForeColor = Color.FromArgb(255, 168, 170, 170); ForeColorLight = Color.FromArgb(255, 188, 190, 190); ForeColorDark = Color.FromArgb(255, 148, 150, 150); TextColor = Color.FromArgb(255, 224, 226, 226); Font = new System.Drawing.Font("Segoe UI", 8F, System.Drawing.FontStyle.Regular, System.Drawing.GraphicsUnit.Point, ((System.Byte)(0))); break; default: break; } } } }
