The could be a mite of some sort. If you touch them with a needle and they jump definitely springtails. A 20x hand magnifying lens would give more than enough for a more positive look.
Springtails come in assorted colors and shapes depending on the family. Colors range from translucent white to blackish with various shades of blue-gray and anything between bright yellow and red. I have some that have a metallic gold/silver color that like my tropical tank. Some are soft bodied looking and others have a harder exoskeleton look to them.
Just some examples of the extremes of body type, shape and color:
