They are the same color as nails, not very deep but definitely noticable. These ridges are especially noticable on the bed of my thumbs and also on the toenails of the big toes. Other fingernails/toenails don't seem to have ridges, maybe just a few small ridges on index finger nails.
Horizontal ridges and white lines on nails are seen in trauma to nail bed, kidney diseases, pellagra or Vit B3 deficiency, low protein, arsenic poisoning, and liver diseases. Hence a kidney and liver function test should be done.
