Colour, Hue, Saturation, and Brightness

Did you know that the Apple II, launched in 1977, was the first PC that had colour? It was a lead that Apple somehow dropped with an incomprehensible twenty-year gap before anybody seem to get their act together. A lead that Microsoft/HP took from Apple with an initiative that would become the de-facto standard most of us use today. Yes, it’s incredible that it’s a standard which has hardly changed in the last 25 years.

Apple did eventually come to the table on this and came back with a new standard, namely display P3 in 2016 — mot only talking the talk but also walking the walk. They launched products that would use it, like the iPhone 7 and others, including the iPad Pro and the iMac.

Indeed, colour today is a far more challenging problem than it ever was, with more devices using different technologies with very different characteristics coming to market.

Anyway, to code, where do we start. Let’s do de-facto. Unsurprisingly, the sRGB as you might expect from a standard developed in 1996 isn’t very intuitive.

Scope of Big Data In India : The Future is Bright

After all, we generate more than 2.5 Qn bytes of data every day, and this figure is going to only increase – thanks to IoT and other advanced technologies. For the uninitiated, IoT stands for Internet of Things, and it is basically a really bad name for an extremely simple concept.

The idea behind IoT is interconnecting the most commonly used devices and optimizing their usage to make our lives simpler. For instance, taking a very basic example, your electric teapot is linked to your alarm clock so that your tea is ready as soon as you wake up. But don’t be mistaken, IoT isn’t just limited to teapots and alarm clocks, and is instead a vast sea in itself – so if you’re interested, don’t forget to explore more!

Coming back to the discussion, such interconnection of devices over the internet surely increases comfort and convenience but at the cost of data. So, other than social media, search engines, and whatnots, even your electric teapot is a source of data.

This data, all of this combined, is precisely what forms Big Data.

And if you’re with us so far, you’d have realized how inevitable Big Data is, and how essential it is to know how to tame it – for the success of any business.

This enormous increase in data is what has given birth to Data Science, which has further branched into Machine Learning, Artificial Intelligence, Deep Learning, and more. All of these technologies are for businesses to make sense of their heaps of data and derive insights from it.

Therefore, it shouldn’t come as a surprise that the global Big Data and business analytics market stood at US$ 169 billion in 2018 and is projected to grow to US$ 274 billion by 2022. Moreover, a PwC report predicts that by 2020, there will be around 2.7 million job postings in Data Science and Analytics in the US alone.

These stats only reinstate the fact that the jobs in Big Data are increasing, and as Big Data increases, so will the opportunities. It’s because of that very reason that many mid-career professionals are switching to Big Data, and many freshers are aclimatizing themselves with Big Data tools and techniques to get a jumpstart in their career.

Now, if you’re either of the two, you might often wonder about the precise future of a career in Big Data. You might wonder if this Big Data wave will be shortlived, or is it here to stay.

Our stance is clear, and we’ve walked you through numerous statistics to support our claim. Now, let’s walk you through how the future looks for a career in Big Data.

Extend the maya channel box with searchability and colour for python

maya-channel-box-plus

channel-box-plus will add search-ability over its attributes, and it will colour user defined attributes, making them easier to distinguish. With the threshold argument you can determine when to switch between colours, the higher the threshold the more the 2 attributes will have to match up to stay the same colour, this value can be adjusted using the colour settings that are added to the native channel box menu.

Installation

Extract the content of the .rar file anywhere on disk.

Drag the channel-box-plus.mel file in Maya to permanently install the script.

Why are we colouring in wireframes?

I was recently involved in a debate around why some wireframes (which were definitely not UI screens) were not 100% greyscale. This got me thinking — when is it ok to use colour in wireframes, and when is it going to cause you problems further down the (design process) line?

Ok, we know the answer is “it depends”, so let’s work this through…

What is a coloured-in wireframe?

Wireframes are traditionally greyscale mock-ups. They are rough representations of interface screens, used early in the design process to communicate initial website or product architecture, journeys, interactions. They are also used in user testing in the form of clickable or interactive prototypes.

The purpose and destiny of a wireframe is to be thrown away (iterated), once it has communicated your intent.

UI design, on the other hand, is the final screen design that goes live — full colour, brand logo, colours, fonts, and live final copy. The purpose of UI design is to be delivered across a live product.

Coloured-in wireframes are wireframes, but containing one or two key brand colours.

So, what is the purpose of a coloured-in wireframe?

Why would you want to put colour in your wireframes?

For some reading this, the idea of using any colour in wireframes is insane. Whereas some teams have mature design systems and never use greyscale — they go straight to UI. See, I told you; it depends.

But if it’s a new project, and you can do whatever you want — why would you not just go greyscale? Well, it’s almost always about stakeholder engagement. Here are a few key scenarios where adding one key colour to a wireframe can help your project:

  • **Your client doesn’t understand wireframes **— I know it sounds patronising, but that’s not my intent. I know it’s our job to make people understand all the things we do. But. Some stakeholders are not web, digital, tech or engineering people and have neither the time nor the inclination to get their heads around A Grey Thing. If you don’t win them over you’re not going to get very far with your design project.

  • You are a long way from UI design — Related to the above, if you’ve been iterating Grey Things for many months, and senior clients are not no longer excited by this, it can sometimes be worth iterating into a higher fidelity prototype. However for reasons you’ll see below, it’s also worth ensuring that you’ve nailed key contentious areas of design and interaction first.
  • **You need to make a point about **colour contrast — If the proposed brand colours are woefully inaccessible, you might want to start showing how they don’t work for your future design — either using toolsor via user testing.

Colouring bash terminal prompt in Linux and MacOS

In this example we are going to change terminal prompt colour. Having different colours for different users and servers can be useful. Having the same colour for all users and servers might sometimes cause people doing wrong things with wrong users and on wrong servers. Colours will tell us who we are and where we are.

After changing colours, you will need to either exit terminal or open a new terminal to see the changes.
