hi
i use corona 3 and color of glass have problem .
Some more info would likely be useful - a screengrab of the glass material (e.g. are you using dispersion? absorption? all that would be answered with a screen grab). Also, any post processing applied (bloom glare, luts, highlight compression?), and what is on the other side of the glass in terms of backplate, light source?
Does it also appear if you reset all VFB post processing settings to defaults? (disable curves, LUT, bloom and glare, and all other options) It looks like a result of post processing.
You can also try increasing absorption distance for your glass, or using refraction color instead of absorption.
