About
The art. The artist. The studio.
Solo artist out of a private studio in Upland, California. Custom builds, flash, black and grey, fine line.
Will Martinez
Tattooing has never been just a job — it's a craft built on years of discipline, late nights, and the relentless pursuit of clean work. From the first machine to running a private studio, every step has been about getting better and pushing the art forward.
COLDBLOOD covers the full range — original flash sheets, fully-custom builds, black and grey, fine line, illustrative. By appointment only. Whether you pull a piece off the flash or we design from scratch around your vision, body placement, and the story you want to carry, the work gets the same attention.
The private studio experience means it's just you and the artist — no distractions, no crowds, no rush. One appointment at a time. That focused environment is the difference between a tattoo you like and one you're proud to wear for life.
Located in Upland, California, COLDBLOOD serves the Inland Empire and beyond. Whether you're looking for black and grey realism, fine line work, bold color, or something completely unique — it starts with a conversation.
