	`function FracToColor(Fraction: real): TColor; overload;`
`FracToColor` converts a fraction between 0 and 1 to a color using the selected TModel.ColorScheme, ColorCycles, and TModel.ColorExponent.

	`function FracToColor(Fraction: real; ColorScheme: TUserDefinedColorSchemeItem): TColor; overload;`

Properties

	`property ColorCycles: integer read FColorCycles write SetColorCycles default 1;`
`ColorCycles` is used to specify how many times the range of colors specified by ColorScheme is repeated when assigning colors to grid cells or contours.

	`property ColorScheme: integer read FColorScheme write SetColorScheme;`
`ColorScheme` is used to specify which color scheme is used to color grid cells or contours. See FracToColor.

	`property ColorExponent: real read FColorExponent write SetColorExponent;`
`ColorExponent` is used to adjust the colors.

	`property OnChange: TNotifyEvent read FOnChange write FOnChange;`
