Subtle Porcelain Veining Modification

I need a skilled artisan to modify the veining on my porcelain wall tiles. The goal is to make the existing veining more subtle.

Key Requirements:
- Muting or adding veins for a refined look
- Preference for thin, delicate veins
- Veins should be muted to light beige

Ideal Skills and Experience:
- Expertise in tile modification
- Strong eye for subtle design changes
- Experience working with porcelain and color matching

The matched porcelain slabs has created a wolf’s face, which we do not like. We would like to slightly modify the porcelain veining by muting and or adding veins with paint to eliminate the wolf’s face. See the attached photo.
