BLUE - A Colourful History

Administrator from Curtain Clean BOP Ltd

The color blue is associated with two of Earth’s greatest natural features: the sky and the ocean. But that wasn’t always the case. Some scientists believe that the earliest humans were actually colorblind and could only recognize black, white, red, and only later yellow and green. As a result, early humans with no concept of the color blue simply had no words to describe it. This is even reflected in ancient literature, such as Homer’s Odyssey, that describes the ocean as a “wine-red sea.”


Blue was first produced by the ancient Egyptians who figured out how to create a permanent pigment that they used for decorative arts. The color blue continued to evolve for the next 6,000 years, and certain pigments were even used by the world’s master artists to create some of the most famous works of art. Today it continues to evolve, with the latest shade discovered less than a decade ago. Read on to learn more about the color’s fascinating history.


There’s a long list of things we can thank the ancient Egyptians for inventing, and one of them is the color blue. Considered to be the first ever synthetically produced color pigment, Egyptian blue (also known as cuprorivaite) was created around 2,200 B.C. It was made from ground limestone mixed with sand and a copper-containing mineral, such as azurite or malachite, which was then heated between 1470 and 1650°F. The result was an opaque blue glass which then had to be crushed and combined with thickening agents such as egg whites to create a long-lasting paint or glaze.

At-Home Fire Safety Checklist

Fire and Emergency from Fire and Emergency New Zealand

With everyone staying home, it’s now more important than ever for everyone to be fire-safe. People can find information on our website - fireandemergency.nz...

We’re heading into winter, and with households self-isolating together, there’ll be more cooking at home, and more use of open fires, heaters, and dryers - all things which can increase fire risk.

New Zealanders can be confident that Fire and Emergency is well-prepared and ready to respond to emergencies as usual during the nationwide self- isolation period.

Please call 111 if you have a fire, we will ask you whether anyone at the address is self-isolating or has a confirmed case of COVID-19. Where this is the case, we already have necessary measures in place to ensure everyone’s safety including protective clothing, gloves, masks, safety glasses and mask.

Our sweet pea seeds send out, April issue and Get Growing

Mei Leng Wong Reporter from NZ Gardener & Get Growing

Dear neighbours and NZ Gardener family,

Our April issue should be with our subscribers now and available in supermarkets and service stations (having been distributed prior to the lockdown restrictions). Whether or not it's on the stands yet is a bit patchy ... but then the incredibly brave and hard-working supermarket staff have quite a bit on their plate right now so I understand if there is a delay! Please, please, please everyone ... don't go out to buy it! Normally of course we love you buying NZ Gardener but right now it's far more important that you stay home and stay safe. (You can buy a copy with your online shopping though! That's safe and I think we are all in the market for something uplifting to read right now).

In this issue we offered to send out sweet pea seeds to any reader who sent us a SSAE. Just to reassure you, we will still send out sweet pea seeds to any reader who is keen to participate. We are just not quite sure when! Ignore the dates in the magazine of when you needed to send the envelope in by - that has been indefinitely extended. But we cannot wait to send you the seed and for those flowers to bloom as by then we will be well through this or even have it behind us. And keep letting us know what you are sowing and growing, send in pictures of your harvest, your flowers or what you are sharing.

We always love hearing from NZ Gardener readers but now when we are all staying apart that connection means more than you can imagine. Stay home, stay safe and stay in touch everyone. For the most updated gardening advice, subscribe to our digital e-zine Get Growing, which will be delivered to your inbox completely free.
