Immersive but distinguishable suspicious Sand and Gravel

The default textures for suspicious gravel and suspicious sand are way too similar to regular sand and gravel, making Archaeology frustrating. All the existing texture packs I found were super lazy and just drew an entirely too obvious red or black border around the blocks. That destroys all the fun of Archaeology. So I made my own!. This one aims to keep things immersive - but not frustrating. Enjoy!
