Yeah, your edit pretty much nails it. The majority of optical imaging satellites use near-infrared in addition to the classic red green & blue channels (& a wider one called panchromatic). Near-infrared is extremely good at seeing plants and vegetation, so the bright red parts will typically be densely vegetated areas like fields and forests.
Looks like these particular images come from GEOSAT and Airbus (I’m guessing one of the Pleiades satellites)
