Adult Psychology Coloring Books

I’m putting together a series of three printable colouring-in books that double as concise study guides for adult learners. Each book will be 15 interior pages (plus a simple cover that mirrors the theme), delivered in high-resolution PDF ready for print-on-demand.

1. Human Psychology – an overview that weaves together key cognitive, behavioural and humanistic theories.
2. Introduction to Psychology – a Psych 101 primer that distils foundational concepts, terminology and famous experiments.
3. Feelings & Emotions – practical insight into how emotions arise, are classified and can be regulated.

Every spread needs brief, accurate text on the left-hand page and a full-page, realistic illustration on the right that users can colour. The text should be written in clear, plain language but still reference the correct theorists, models and terminology so the reader learns while they relax.

I’m specifically asking for:
• 45 pages of original instructional copy (around a paragraph per page, citation-level accuracy).
• 45 matching, realistic line illustrations suitable for colouring (clean black outlines, no grey shading).
• Source files for the artwork (layered AI, PSD or SVG) plus press-quality PDFs for each finished book.

If psychology excites you and you have a knack for turning complex theory into engaging visuals, I’d love to see a quick sample: a single page on classical conditioning with its paired illustration will help me gauge fit.
