Convert your TColors to hex strings

[bholas]

In Delphi, color is often represented using the TColor object. In HTML documents, color is usually represented using a 6 character hex string. Following function will convert TColor type color values to "Internet-style" color codes:
{
Return TColor value in XXXXXX format
(X being a hex digit)
}
function
TColorToHex( Color : TColor )
: string;
begin
Result :=
{ red value }
IntToHex( GetRValue( Color ), 2 ) +
{ green value }
IntToHex( GetGValue( Color ), 2 ) +
{ blue value }
IntToHex( GetBValue( Color ), 2 );
end;

Need to convert a hex color string to a TColor variable? Try this:
{
sColor should be in XXXXXX format
(X being a hex digit)
}
function
HexToTColor( sColor : string )
: TColor;
begin
Result :=
RGB(
{ get red value }
StrToInt( '$'+Copy( sColor, 1, 2 ) ),
{ get green value }
StrToInt( '$'+Copy( sColor, 3, 2 ) ),
{ get blue value }
StrToInt( '$'+Copy( sColor, 5, 2 ) )
);
end;
