Ubiquity Partition Colors

[geistschatten]

Hey, I didn't know where else to post this, but I'm making an Ubuntu-based distribution and have been trying to remove Ubuntu's branding since brown doesn't go well with dark blue and black. So my question is, how do you change the color of the partitions during the installation? For example Mint has a mint-colored partition saying Linux Mint, and Ubuntu has a brown-ish partition saying Install Ubuntu or Ubuntu...I forget. Anyways, I want mine to be dark blue.

Thanks for any help. I can post a screenshot if necessary.
