Let customers speak for us
from 157 reviewsKate’s paints are heavily pigmented and a joy to use! I highly recommend her colors!

This color reminds me of lemon chiffon ice cream… I absolutely love it! 💕

A lovely soft, dusty pink with a moderate value range that fits well into my ochre inspired pallet. It has a vintage, earthy feeling. Smooth consistent blush color, great for botanicals, landscape and I imagine it could be quite nice for portraits.

Beautiful bursts of quality color

Absolutely beautiful color explosions !! So much fun, make you smile

A perfect name for these magical pigments! The results are outstanding and bring a heavenly aura to my watercolor art. The addedl gift of a sample of your upcoming Royal Gold pigment paint was a wonderful surprise. This is an amazing addition to your selection and I look forward to purchasing more soon.

A delightful accent color! On paper it is the bright yellow-green of new maple leaves in the spring, appearing more green in the pan. Smooth and creamy (like all RM paints), it rewets easily and a little goes a long way. Just barely opaque when painted over line work.

Absolutely gorgeous and exciting to use!

Finally! I am starting to be able to be organized and specific with my studio time, goals and projects with this studio planner.
This is an awesome planner/organizer specifically for artists, and I love it! I also ordered the brush cloths, very nice quality. I will be ordering more of these. Fast shipping too!

Just love everything about this collection, the colors are rich and granular and the results are so beautiful!
Thank you for always supplying such a premium hand made paint!

I love these watercolors! They are vivid, concentrated, and fun and to use! Can’t wait to try more :)

This color pulls you in and then surprises you with a twist!
