The Mosasaurus watercolor color palette
This balanced, painterly palette is anchored by Deep Slate (#537C9A), the dominant wash across the mosasaurus set. Light Cyan and Pale Olive carry the midtones, and Deep Cyan (#132935) grounds the shadows and outline work. Together they capture the soft, layered look of the original hand-painted artwork — copy any value below, or export the whole set as CSS variables, an Adobe ASE, GIMP or Procreate swatch file.
Cross-stitch & marker conversions
Because UsefulPix is built for crafters, every color is already matched to the nearest physical thread and marker, so you can take this palette off-screen. For embroidery and cross-stitch, the closest DMC floss are DMC 825 (Blue Dark), DMC 311 (Wedgewood Ult VyDk), DMC Ecru (Ecru), DMC 820 (Royal Blue Very Dark). For marker and Copic work, reach for Copic B97 (Night Blue), Copic C-9 (Cool Gray No.9), Copic W-0 (Warm Gray No.0), Copic C-10 (Cool Gray No.10). These are perceptual nearest-matches (CIEDE2000), so treat them as a faithful starting point and check a physical shade card for critical work.
