Original: In the Republic of Ireland, lemonade refers to the carbonated, lemon-flavored soft drink (as in the UK) but is further sub-divided into white (clear) lemonade and red lemonade. White lemonade equates to the colourless fizzy lemonade common in many countries, while red lemonade is particular to Ireland.
Simplified: Pink Lemonade usually means lemonade that is pink.
