Using this palette

Where warm-neutrals leans beige, this ramp carries a consistent blue undertone through every step, which reads as clean and clinical rather than cozy — the difference matters for brand fit: healthcare, tech, and professional-services sites tend toward cool neutrals, while hospitality and food brands lean warm. #5C6670 clears AA for body text against the three lightest tones; treat #A3ADB5 and up as backgrounds and dividers only. Like warm-neutrals, this is a foundation rather than a full palette — pair with one genuine accent color (a blue or teal reads most native against this base) rather than trying to build hierarchy from the neutrals alone.
