• string: length prefixed string in UTF-8 encoding, the prefix contains the encoded length as a 7-bit encoded unsigned integer

• byte: 8-bit unsigned integer

• uint16: 16-bit unsigned integer

• uint32: 32-bit unsigned integer

• single: 32-bit floating point number

Structure

// overall file
ColorLibrary {
	string			header signature			// always "MRC color library"
	uint16			file version
	string			LibraryName
	uint16			padding						// always 0
	
	uint16			nCategories
	ColorCategory	Categories[nCategories]
	
	uint32			EOF signature				// always 0
}

// category
ColorCategory {
	string			CategoryName
	uint16			nColors
	ColorItem		Colors[nColors]
}

// color
ColorItem {
	string			ColorName
	byte			Format						// 0: sRGB 8-bit, 1: sRGB, 2: linear RGB
	byte/single		Red							// byte for Format = 0, single otherwise
	byte/single		Green						// byte for Format = 0, single otherwise
	byte/single		Blue						// byte for Format = 0, single otherwise
