★★★★★

The red one genuinely changed how I edit. I keep my messy drafts in green and do the cutting in red. Sounds silly, works.

White ink on the black pages feels like writing on a chalkboard you actually want to use. Brilliant for late-night ideas.

Started with the blue for brainstorming and now I own all four. The paper handles the gel pen with zero bleed. Lovely object.

FAQ

Both effects we cite are from peer-reviewed journals: Mehta & Zhu in Science (2009) for red and blue, and Lichtenfeld et al. in PSPB (2012) for green. We describe what the studies actually found and do not claim guaranteed results for any one person.

Each page is saturated colour, so a normal pen would vanish. Every Chroma ships with a white gel pen designed for the paper: high contrast, smooth flow, minimal bleed.

Dot grid as standard. It is the most flexible: structure when you want it, freedom when you don't. Blank and lined editions are on the roadmap.

98 coloured pages (49 sheets) of 100gsm bleed-resistant paper, in A5 (148 × 210 mm), pocketable but roomy enough to think on.

Please do. Plenty of people keep blue for open thinking, green for ideas, red for editing and black for deep work. Buy any two or more and UK shipping is on us.
