Im confused you want light blue pillows or light blue pillows with the color of the leather mixed in?

Theres plenty of light blue pillows a simple Google search

I’m looking for pillows that has blues and a touch of the sofa color

This pillow is the closest that I have come to the colors.

I wish it had more blue.

That pillow looks great!

You dont need more blue ...imo design is about complimenting ...going too matchy matchy can actually have the opposite effect

A room looks more put together if you can use the same colors but in varying levels of saturation

Especially with the aesthetic you have its not like a post modern look where super saturated pops of color are of the design style.

You can also add a solid blue pillow next to that patterned one maybe in a different shape
