Light green. Beacause I like green and if it's like an apple green, it's WONDERFUL forme^-^ Also pink is a bit to "Girly" for me. But it's important in which context do you mean these colours. If it's for clothes I would REALLY prefer light green. But if I mark a text at school, I would also mark it with pink. But general: Light Green! ^-^ Thanks for asking; Greetings :)
