In BC when they were at their worst the sky was dark yellow and the sun was a very dark blood red. It was like something I’d never seen before. Think the light level in Seattle during an extremely overcast day with a low ceiling, but everything you look at has been coloured yellow by the sunlight passing through the smoke. It looks a lot like photos from the various Mars missions.
(I'm not sure what "yellow" means where you're at. It's "healthy" according to https://www.airnow.gov/aqi/aqi-basics/).
