I don't know where is your balcony facing. If the tenuifolia Amethyst color is fading away, it show your place is too shady. Try to relocate to other place which is sunnier. Actually..... I'm having a feeling the bamboo blinds is blocking away 70% of sunlight. Do let me know how it goes.
Btw, the other plant is a capitata. Not sure which type though.
