Colour Changing Mugs | Heat Sensitive Printed Mugs Newcastle

Surprise and delight with our personalised colour changing mugs from Signs Shop in Newcastle. These amazing heat-sensitive mugs appear completely black when cold, but reveal your hidden design, photo, or message the moment hot liquid is poured in. So, whether you’re ordering a unique gift for a loved one or a standout promotional item for your business, colour changing mugs create a wow moment every single time.

Because every mug is individually printed with your custom design, they make a truly one-of-a-kind gift for birthdays, anniversaries, Christmas, and more across Newcastle and the UK.

How They Work

The mug starts black when cold. As soon as you pour in a hot drink — coffee, tea, or hot chocolate — the black coating fades away to reveal your hidden artwork, photo, or message underneath. When the mug cools down, it returns to black again, ready for the reveal next time.

Frequently Asked Questions

How does a colour changing mug work?

The mug has a heat-sensitive coating that appears black when cold. When you pour in a hot drink, the coating becomes transparent, revealing your custom design underneath. As the mug cools, it returns to black again.

Can I order just one colour changing mug?

Yes. We print from as little as one mug, so you can order a single personalised colour changing mug without any minimum quantity requirement.

Is the colour changing effect permanent?

Yes. The heat-sensitive coating and your printed design are both durable and long-lasting. The reveal effect works repeatedly — every time you pour in a hot drink.

How quickly can I get my colour changing mugs delivered?

We offer free UK mainland delivery on all orders, with fast production turnaround so your mugs arrive quickly wherever you are in the UK.
