I love the other colours that you used to pair with the featured colour, yellow. The subtle use of yellow highlights the shapes of the pattern nicely and accentuates the shades of blue and green. Using black not only matches well with yellow but creates separation that in turn adds more pattern of colour to the design. I also like the idea of the black hole in the background and all of the additional hourglasses spinning into the center!

Thanks for entering and supporting the #zencolouringcontest. Sorry for the delayed acceptance!

Thanks for naming Blue! as your suggestion for next weeks featured colour!
