Works well on recent Android versions, as it colours the nav bar a nice, even darker red. Is a good darker colour without any blue, but still easily discernable from the black menu bar of private mode, making it much less disruptive for reading dark pages at night, without compromising UI intuitiveness.
Great simple, practical theme.

This is Perfect. Simple solid color with great contrast. Very close to FireFox's Orange flames, without being to bright for the aging eyes.

Es un tono de rojo muy bonito. Es un tema muy simple pero muy bello.

Es mi color favorito y me gustó mucho el tema

This theme provides a nice, burgundy color for my toolbar and background.
