-// Package blush reads from a given io.Reader line by line and looks for

-//
-// Blush struct has a Reader property which can be Stdin in case of it being
-// shell's pipe, or any type that implements io.ReadCloser. If NoCut is set to
-// true, it will show all lines despite being not matched. You cannot call
-// Read() and WriteTo() on the same object. Blush will return ErrReadWriteMix on
-// the second consequent call. The first time Read/WriteTo is called, it will
-// start a goroutine and reads up to LineCache lines from Reader. If the Read()
-// is in use, it starts a goroutine that reads up to CharCache bytes from the
-// line cache and fills up the given buffer.
-//
-// The hex number should be in 3 or 6 part format (#aaaaaa or #aaa) and each
-// part will be translated to a number value between 0 and 255 when creating the
-// Colour instance. If any of hex parts are not between 00 and ff, it creates
-// the DefaultColour value.
-//
-// Important Notes
-//
-// The Read() method could be slow in case of huge inspections. It is
-// recommended to avoid it and use WriteTo() instead; io.Copy() can take care of
-// that for you.
-//
-// When WriteTo() is called with an unavailable or un-writeable writer, there
-// will be no further checks until it tries to write into it. If the Write
-// encounters any errors regarding writes, it will return the amount if writes
-// and stops its search.
-//
-// There always will be a newline after each read.
