For the kitchen - roller or Roman. But I can’t really see what aesthetic your after. Roman shades are and will take on a much more traditional style.

For what seems to be the living room. I would leave the triangular window open and either match to the kitchen. Or do a roller shade with curtains over it.

Are roller shades outdated ?

Roman shades for sure! There are 4 different configurations of Roman shades so you can select the style that best goes with your level of contemporary or traditional. You can have any thing from a creamy linen to a bold red pattern. Some are fixed and others open and close.
