Doing a quick Google search of Sigma cameras, it appears as though their sensors appear to be a deep red color, while most (what I think to be) traditional cameras appear to have a greenish-blue color to them. I'd guess this would be because more traditional lenses have more green sensor than red or blue?

Here's the camera, looks expensive but maybe that's normal for cameras. https://www.sigmaphoto.com/cameras

how does this impact the design and functionality of color sensors, like the Foveon X3, in terms of color accuracy and image quality?

Apparently long-wavelength photons penetrate deeper in silicon despite having less energy because they're less likely to excite the electrons in the silicon (they don't have enough energy), and thus aren't absorbed. This is also why radio waves can go far and through materials!

Looking into the Foveon X3 sensor in Sigma cameras - the unique design that stacks photodetectors vertically, captures red, green, and blue light at different depths. Since it grabs all three colors at each pixel without needing the usual color filters, you get richer colors and sharper details right off the bat. It's a cool twist on capturing images, leveraging how deeper reds go into silicon compared to blues.
