i think all her albums have dark song and colourful songs on there cause the fame it had just dance and summer boy the where colourful and brown eyes was dark - the fame monster most songs was dark but i don't think telephone was that dark but she mad it have a dark theme to it in the video - born this way had judas and heavy metal lover and that they where dark and fashion of his love was colourful if u get what i mean x
I din't agree that Born This Way is dark. Gaga has said herself that it's that kind of album to listen to and party, it of course has darkness, but The Fame Monster is much more darker! Just my thoughts :)
If it's very colorful, it may come a childish look, e.x. Nicki Minaj. I don't really want ARTPOP to be that colorful - I think Gaga is always so classy in black and white. Of course I love her colorful outfits too but I wish she would continue the BTW era's color palette.
I think The Fame Monster has a much darker message, because it's about your fears. While Born This Way is about being born for something you should feel proud...
