Colour Palette Generator
Build a harmonious colour palette from any starting colour. Choose a harmony rule and get matching colours with hex codes you can copy with a click.
How to use it
Colour harmonies are sets of colours that look pleasing together because of their fixed relationships on the colour wheel. This generator converts your base colour to HSL, rotates its hue by the angles each rule defines, and returns the resulting colours as hex codes. Click any swatch to copy its code. Complementary colours sit opposite each other (180°) for high contrast; analogous colours are neighbours (±30°) for a calm feel; triadic and tetradic spread evenly around the wheel for balanced, vibrant schemes; and monochromatic varies only lightness for a subtle, cohesive look.
Frequently asked questions
- What does compounding frequency change?
- More frequent compounding (e.g. monthly vs annually) earns slightly more, because interest is added to the balance more often and then itself earns interest.
- Does this include regular contributions?
- No — this models a single lump-sum deposit. For recurring monthly contributions, use the SIP calculator; for paying down a loan, see the loan calculator.
- Is my data sent anywhere?
- No. The calculation runs entirely in your browser; nothing is uploaded.
- Why does compound interest grow faster over time?
- Each period's interest is added to the balance, so later periods earn interest on a larger and larger amount. Early on the effect is small, but because the growth compounds on itself the balance rises faster the longer the money is left invested, which is why time is the biggest factor in compound growth.
