Theia just published the first Venµs images today, including a beautiful view of the Pyrenees. Once you have dezipped/untared/unzipped the files you can make a true color composite using the command:gdal_translate -b 7 -b 4 -b 3 -scale 0 300 0 255 -ot byte VE_VM01_VSC_PDTIMG_L1VALD_ES_LTERA_20180419.DBL.TIF myColorCompo.tif
I tend to focus on the snow so I stretched the colors between reflectances 0-1000 instead of 0-300:gdal_translate -b 7 -b 4 -b 3 -scale 0 1000 0 255 -ot byte VE_VM01_VSC_PDTIMG_L1VALD_ES_LTERA_20180419.DBL.TIF mySnowColorCompo.tif
First, I was a bit puzzled by the orange shade in the northern part of the image. We inspected carefully the image with Olivier because at this stage radiometric calibration issues are still possible.. 
A month later, the dust layer resurfaced:

Dear Simon, even our cars were covered by orange dust in Pau and in the Western Pyrennees. Yes you need to leave Toulouse for having a look to the real Pyrennean life. Cheers, Bernard

In this case, the orange color came from a new deposit. But in late season, it could have been an old one coming back to the surface because of the melt. Even though the aspect would probably be less uniform in this case as the snow has not the same depth and the same melt rate everywhere.
Here is the picture I took before crossing the Aragnouet Bielsa tunnel on April 21st. Patches of orange and white snow were easily visible. https://photos.app.goo.gl/ASqsYshG3kZZ6xgK6I took almost the same photograph 6 days later when coming back. A lot of melt had occurred. Presence of orange snow was less obvioushttps://photos.app.goo.gl/TXoU4KcSmL8F7WFs6
