Paint Mixing Ratio Calculator
Calculate exact volumes of base paint and tints to mix a custom colour consistently. Essential for tinting your own paint or scaling up a colour you've created.
Why Ratios Matter
When mixing custom colours, always record the exact ratio used. Mixing 'a bit of blue and a bit more white' will never reproduce exactly — ratios like 8:1 (white:blue) let you accurately remake the same colour in any batch size.
Keeping Records
Note: the brand and product line of each paint, the exact colour names and codes, the ratio, and the batch size. Store a small test card with the dried paint alongside your notes. Even a 10% variation in ratio can produce noticeably different results.
Colour Theory Basics
Adding white (tinting lighter) changes value but can shift the hue. Adding complementary colours dulls a tone. Small amounts of dark colours dramatically change lighter ones — add dark to light, not light to dark. Start with less tint than you think — it's easier to add than remove.
Energy Efficiency Priorities
Home energy improvements should be prioritised by payback period. Quickest payback: draught proofing (£50-200 cost, saves £60-100/year — under 2 years). Loft insulation (£300-500 DIY, saves £150-200/year — 2-3 years). Switching to LED lighting (under £100, saves £40-60/year — under 2 years). Longer payback: cavity wall insulation (3-5 years). New efficient boiler (5-10 years). Solar panels (7-15 years). Heat pump (10-25 years at current energy prices). For homes eligible for ECO4 funding, the pa
