Marrs green

Marrs green is a science topic covered in the lgStudy science library. This page brings together a partial reference excerpt, illustrations, worked examples, real-world applications and a short study plan, so you can understand Marrs green rather than just read about it. In short: Marrs green is a shade of green that in 2017 was named "The World's Favourite Colour" in a major global survey by the British paper merchant G . F Smith.

Key takeaways

Marrs green belongs to science; place it in that map before memorising details.
Learn the definition first, then one example that makes the definition concrete.
Connect Marrs green to a quantity you can measure, compute or draw — that is where exam questions come from.
Reproduce the core statement of Marrs green from memory before moving on to harder problems.

Reference excerpt

Marrs green is a shade of green that in 2017 was named "The World's Favourite Colour" in a major global survey by the British paper merchant G . F Smith. It is a rich teal hue. The colour was submitted by Annie Marrs, a UNESCO worker from Dundee, who was inspired by the River Tay. In alternative design accounts, Wayne Peter's contributions to the shade's promotion are also noted. The survey received 30,000 submissions from over 100 countries via online polling after it was launched in January 2017. It became the 51st shade of the un-coated paper range Colorplan.

Worked examples

Example 1 — a first encounter with Marrs green

Start with the simplest possible case. Write down what Marrs green claims or describes in one sentence, then invent the smallest concrete situation in which that sentence is true. In science, the smallest case is usually a single object, a single equation or a single measurement. Check that every symbol or term in your sentence has a meaning in that case.

Example 2 — changing one variable

Take the situation from Example 1 and change exactly one quantity: double it, halve it, or set it to zero. Predict what should happen to Marrs green before you calculate. Comparing your prediction with the result is the fastest way to find out whether you understand the idea or only the words.

Example 3 — an exam-style question

Typical questions about Marrs green ask you to (a) state it precisely, (b) apply it to given data, and (c) explain a limitation. Practise writing all three answers in under five minutes; the third part is what separates a full-mark answer from an average one.

Applications of Marrs green

In research: Marrs green appears in science research whenever the underlying quantities have to be modelled precisely. Papers usually cite it as a starting assumption and then explore where it breaks down.
In technology and industry: Engineering practice reuses Marrs green in design rules, simulations and safety margins. Knowing the idea lets you read a specification sheet and understand why the numbers look the way they do.
In the classroom: Marrs green is common in secondary-school and first-year university syllabi. It links to neighbouring topics Color stubs, Shades of blue, Shades of green, so understanding it makes those chapters shorter.
In everyday life: Look for Marrs green outside the textbook — in sport, cooking, traffic, electronics or the sky above you. An example you found yourself is remembered far longer than one you were given.
