So for clarity, I wiki'd Monochromatic colours and this is what I got: "Monochromatic colors are all the colors (tints, tones, and shades) of a single hue.Monochromatic color schemes are derived from a single base hue and extended using its shades, tones and tints. Tints are achieved by adding white and shades and tones are achieved by adding a darker color, gray or black."
So that my lovelies is what I did. I chose a peacock blue shade acrylic and added water and black or white to create the amoeba like watercolor spots on each nail in a lightening order from darkest navy to baby blue.
I'm really pretty fascinated with the final look...it's pretty cool! Cheers all,
