this contains new colour for the concrete airfield plates....which to many people seem to be too bright and easily seen from afar..

this is global...so all airfields in all maps using these plates will have their colour changed....but you can easily disable this by putting a - at the front of its folder name....-airfieldplate

also new ground (grass)...which looks more like puddles and smears in the mud/grass closer up

and a less bright sands of time one

if you don't like them just delete that folder...ground/desert/concrete
