User can choose how the color will be returned. .DESCRIPTION Present a dialog to the user and allow them to select or define a color. User can choose how the color will be returned. .PARAMETER R The Red color value. Defaults to '0'. Valid range 0-255.

Can be passed from the pipeline by property name. .PARAMETER B The Blue color value. Defaults to '0'. Valid range 0-255. Can be passed from the pipeline by property name. .PARAMETER AsHashTable Switch that will present the results of 'R,G,B' as a hashtable as opposed to a psobject .EXAMPLE New-ColorPicker -R 20 -G 45 -B 255 Will present the user with a color dialog pre-populated with 23, 45, 255 .EXAMPLE New-ColorPicker -verbose VERBOSE: Starting [New-ColorPicker] VERBOSE: R [0] G [0] B [0] VERBOSE: Ending [New-ColorPicker] R G B - - - 0 128 192 Assuming that they entered the color 0, 128, 192 and selected 'Rgb' as the output type. .NOTES The user can select how the result will be returned to them: * Hex - where the color will be returned as 6 hexadecimal characters in the form: 'RRGGBB' * RgbString - where the color will be returned as 3 integers separated by a comman 'R,G,B' * Rgb - where the color will returned as a psobject with 3 properties: R, G, B If the user selects 'Cancel' from the dialog box no value is returned. #> [CmdletBinding()]
