-Colour palette prompting notes for [Raphael AI](https://raphael.app) - free AI image generator https://raphael.app
+Colour is the fastest way to make a set of images feel related. These notes cover how I steer palettes in [Raphael AI](https://raphael.app).
+
+## Name a palette, not just one colour
+"Muted palette of sage green, sand and terracotta" works better than "green".
+
+## Borrow from real materials
+"Colours of weathered copper", "faded denim and chalk", "autumn maple leaves" are concrete references the model understands.
+
+## Set the temperature
+"Cool blue hour light" versus "warm golden hour light" changes every colour in the frame at once.
+
+## Limit saturation
+"Desaturated", "pastel", or "high contrast, saturated" are powerful single words. For brand work, desaturated images often sit better next to text.
+
+## Check consistency
+When building a series, keep the palette sentence identical across prompts and change only the subject.
+
+## Accessibility note
+If images carry information, do not rely on colour alone; add labels in your layout.
