This is what I have created as a cover for the story that I will be illustrating. I have taken inspiration for this from the like in the book that says "Ruby holds up a a jar: six black tadpoles squirm in an inch of water". I have also tried doing this piece in the style of Jon Klassen, by cutting out shapes out of watercolour textures and layering them in photoshop.
Triadic Colours
Complementary Colours
Monochromatic Colours
I have decided to stick to monochromatic colour scheme for my book cover because it gives off a calmer feel to it and it relates better to the story where the colour blue is often repeating.
Monochromatic blue colour scheme links better to the title it self; 'The Deep', which gives the viewer an image of water/ocean etc.
