Cool Grey Colour Palette

About this palette

The Cool Grey colour palette brings together a set of shades that can be used across interiors, fashion, branding, websites, presentations and creative projects. It gives you a starting point for understanding how this colour behaves alongside lighter neutrals, deeper accents and supporting tones.

Use this palette when you want a ready-made colour direction rather than starting from a blank canvas. The colours included are #64748B, #CBD5E1, #F8FAFC, #0F172A, making it easy to copy the values into a design tool, CSS file, mood board or visual concept.

How to use this palette

• For interiors: use the lighter shades for walls or backgrounds, then bring in the deeper shades through furniture, artwork, textiles or smaller accents.
• For websites: use the strongest colour as an accent, the lightest colour as a background and the darkest colour for readable text.
• For branding: pick one dominant colour, one neutral and one contrast colour so the palette feels recognisable rather than crowded.
