Sketch SVG It appears that the SVG has different border rendering settings so borders are not inset. You may need to clean it up a bit.
Below are some Mastodon headers I made for my Mastodon profile. All color schemes are taken from the @accessibleColors bot which posts random matching accessible colors on Mastodon.
Feel free to use these headers for any non-commercial thing you want.
