I think Clearview sells tinted shields. It used to be not colors, just a non glare tint (close to clear).
However, their website now lists light and dark gray for the Interstate. (hit the color drop-down box)
https://www.clearviewshields.com/motorcycle-windshields/honda/honda-cruisers/valkyrie-interstate-shields/I can personally recommend their 5" wider shield (2.5" on each side).
Also, they list a bunch of heights, but I think you can order it any height you want.
15.5" is stock (with the half inch below the chrome bezel for mount to fairing)
Also, you may want to preorder the 4 anchors used in mounting interstate shields; they often need replaced and often spin in the fairing plastic. You may need
JB Weld too. Inserts for fairing, Honda part #90316-MJ1-000
