Do you notice the colours when you’re watching a film?

You might not, but someone’s thought carefully about them. Not just the colour of costumes, props and sets, but the colour of the light and the overall colour balance of each shot.

Colours are used to give an atmosphere and to reflect mood. They can relate to characters. The overall colour will change throughout – there may be a colour arc that relates to the story arc or to a character’s arc. Pixar create “colour scripts” for each film – Lou Romano has posted a lot of his art for Up (warning, spoilers – be careful if you haven’t yet seen the film) including first pass colour scripts for Act I and a full colour script.

Now, in The Lost Book we had a different challenge. We didn’t know what the story would be, or who the characters would be, or what their stories would be. It meant we couldn’t plan colours or sketch a colour script. But, we still wanted to use colour as best we could.

Episode 1 stills

In the first episode we set up some simple contrasts of colour and light. Dark colours and red were used when the book was stolen. Light colours, especially yellow, and bright light were used when Aileen was in a safe place. Tiny elements of purple/lilac were used to relate to the crime – the tag left on the lectern was purple and the bus set in the final shot, when Aileen discovers that all online copies of the book have also been stolen, features lilac as well as yellow.

Episode 2 stills

We could build on this in episode 2. When Aileen’s talking to Kyle, she’s in a good place (yellows/light) but we’re not sure about Kyle (black). In the bookshop, someone bad has got at the books, so we’re using dark colours, reds and oranges.

Episode 3 stills

By episode 3 we had a baddie – Otto Dafé. His name, with the reference to burning, fitted beautifully with the colour scheme we’d chosen for bad things, so we dressed him in black and made sure oranges and reds surrounded him. Even in episode 4, when he’s in the airport (a space we’ve made light and bright and full of greens – Kyle’s colour and another indication of a safe place) we darken the Otto shots by half-filling the screen with a black mobile phone, and adding orange/red tones in Otto’s books and in the seating in the background.

Episode 4 stills

By episode 4 we also knew that Grazp Pharmaceuticals was responsible for the theft… so it turned out that their corporate colour was purple/lilac. This colour scheme segued into episode 5 where purples and blacks were used throughout – it wasn’t just the darkness that made this the darkest episode, everything about the tones used showed that the characters were in a tight spot.

But, we had a problem. Otto was no longer a bad guy, so his signature colours of red and orange couldn’t be used, and the link between him and those colours previously suddenly didn’t work so well. There wasn’t anything we could do about this, apart from reconceptualise orange/red as the colour range that meant books were in trouble.

Episode 6 stills

The final episode showed a marked change in atmosphere. The scenes at the Sheep Heid Inn that frame the episode use bright light, yellows and greens. Both Aileen and Kyle are there, they’re safe and happy, no books are in danger. We used reds and purples in the early flashbacks, but gradually worked back through to yellows and greens as the mood lightened and the crime was solved.

Colours used throughout The Lost Book

Looking at all the stills, there’s quite a pleasing colour arc and the colours worked well to reflect the mood. But, Otto’s transition from baddie to goodie was very hard to handle!

(Oh, and on the subject of colours, this might amuse you as an insight into how obsessive we are about this sort of thing!)

Still frames from The Lost Book episode 6 - Sheep Heid, Aileen's Mum in the NLS, Otto in the VSL

Books are something of a theme in episode 6. To celebrate the Lost Book being found and returned we wanted lots of books. We have two scenes set in libraries and a big bookshelf in the Sheep Heid Inn. We managed to resist the temptation to make all the books individual (I’d have really enjoying thinking up appropriate titles!) and instead decided to go for matching bindings in a few colours. Here’s how we made them…

First up, we created a book model in the computer. In fact, there are two versions: open book and closed book.

3D model of a book - closed and open

Next, the book needed a texture map. We unwrapped the model to get a flat, 2D image and added the binding, endpapers, page edges and title page (1). Finally, some gold lettering on the spine was needed – a simple black and white image allows us to specify where the gold should be added (2).

And, there you have it. Books everywhere!

Watson finds Grazp's "project rejuvenation"

Thought you might like to see a (jaggy!) draft of Watson finding evidence of Grazp’s “project rejuvenation” – a rack of water-filled test-tubes with a note from the lab and the marketing department’s mock-up of a sales brochure.

The last tweaks to the animation, textures and lighting have been made and this shot is ready to be set off to render.

While the computers are working on the rendering, we’ll be going through to Glasgow tomorrow to record the voice track with Cora, Sean and Stephen. It’s all coming together nicely!

The render farm has finished our first shot – Aileen and Lyn in the dojo:

Hurrah!

The music recording session is tomorrow morning – various drafts have been coming through from Alexis all day. It’s all getting very exciting!

We’re rendering our first shots this weekend. This was looking so good that I had to give you a sneak preview:

What is “rendering”? It’s the last stage in creating CGI animation footage and the one stage that the computers do for us.

The computers take all the information we’ve given them, and generate a finished image for each frame of the animation. The process of setting off a render is complex as there is a fine balance between getting high quality images and making sure they don’t take forever to render.

Final rendered frames from Copper Beeches Cafe scene

We use standard desktop computers (with plenty of RAM) and we’re generally aiming for each image – each frame of the animation – to take about 10 minutes to render.

We’re working at 25 frames per second, so 25 images need to be rendered to produce each second of animation. That means 1,500 still images are needed for one minute of animation. At 10 minutes per frame, it will take 250 hours to render one minute’s footage – over ten days.

Fortunately, we have more than one computer to do the work. We have a network of machines linked together, known as a “render farm”. They share the work between them. (Why “farm”? I’ve no idea, and I’ve always wondered. If anyone knows, leave a message.)

Right now, the last few frames of episode 3 are rendering. Most of the post-production work has already been done, so we’ll be ready to produce the final video file as soon as the final frames are complete.
