Activity Guide - Encoding Color Images. Practice with the color pixelation tool. Use the Pixelation Widget to recreate specific colors. Recreate simple color images and describe the difference when using 6 or 12 bits per pixel. Encode colors with hex. The tasks below follow the guided sequence in Code Studio which has tutorial videos followed by specific tasks. The purpose of this activity is only to become familiar with the color pixelation tool, and to practice a little bit, in order to be comfortable enough to start the favicon assignment.
Tutorial Video: How to use the pixelation widget to control color. Task 1: Fill in the last two pixels with the missing colors. Problem: fill in the last two pixels. Optional Practice: change the pixel data so that the blue and yellow pixels exchange locations in the image.
If you mess up, you can always re-copy-paste the bits from this example. Tutorial Video: more bits per pixel for more colors.
Task 2: Experiment with 6-bit color. To start you are presented with the image at right. Tutorial Video: Using hex to type bits more quickly. Task 3: Experiment with Hex.
Make a 4x4 image with bits-per-pixel set to 12 and the tool into hexadecimal mode. NOTE: Using bits-per-pixel colors! Here is the breakdown:.
make 8-bit art!
To make a darker shade, just choose a smaller hex digit for the channel of color you want to affect, such as 3A5 which turns the amount of blue light down. This is to avoid confusion when hex numbers have only decimal digits.
Create an image that looks something like picture shown at right in which. Rewrite this string of numbers from raw format to readable format, and identify or label the sections of bits. How many more colors are available with 12 bits-per-pixel than 6 bits-per-pixel? What happens if you have you an image that has 6 bits-per-pixel and you change it to 12? Search this site. There are more colors.
The colors change because the code is read differently.Keep safe, be healthy, and stay creative during this uncertain time. One-off die-cut, 16x16 stickers. Removable, waterproof and extremely awesome.

The son of man Sticker.In this lesson students are asked to consider how color is represented on a computer and to imagine how it might be encoded in binary.
Students then learn about how color is actually represented on a computer - using the RGB color scheme - and create their own images in an new version of the pixelation widget that allows you use more than 1 bit per pixel to represent color information. After grappling with the prospect of possibly many bits just to represent a single pixel, students are shown how using hexadecimal allows us to represent many bits with fewer characters.
Students use a new version of the pixelation tool to encode an image with color and create a personal favicon. A major outcome will also be understanding the relationship between hexadecimal base and binary base-2and how useful it is to use hex to represent groups of 4 bits.
It's important to realize that using hex is not a form of data compression, it's simply a different view into the bits. The most common color representation scheme - RGB - typically uses 24 bits 3 bytes with 8 bits each for Red, Green and Blue intensities.
And one of the most common ways you see these colors represented is in hexadecimal. The pixelation widget, with its ability to choose how many bits represent the color value for each pixel, can be a very useful tool for showing the utility of hex representations for bits.
The process of rendering color on a computer screen by mixing red, green and blue light is an important concept of this lesson. Another important objective of this lesson is to understand how uncompressed image file sizes can become quite large. For example, even a relatively small image of x pixels is a total of 62, pixels, each requiring up to three bytes 24 bits or color information, resulting in a total of 1.
Thus, interesting connections to compression can be made here, but note that lossy compression and image formats like. Differentiation and accommodations for this lesson. It is likely that many students will come up with an idea like making a list of colors and just assigning a number to each one. That is fine and reasonable. Some students may already be aware of a numeric RGB color scheme.
If they can describe that here, that is fine as well. Regardless of their encoding, students should be thinking about the number of bits they will allocate to the encoding and how that will affect the number of colors that can be encoded. Use a getting started strategy to address these questions for ideas consult: Teaching Strategies for the CS Classroom - Resource.
The way color is represented in a computer is different from the ways we represented text or numbers. With text, we just made a list of characters and assigned a number to each one.
As you are about to see, with color, we actually use binary to encode the physical phenomenon of LIGHT. You saw this a little bit in the previous lesson, but today we will see how to make colors by mixing different amounts of colored light. Following the video, you might address any questions or give students time to complete the video worksheet.
If you are comfortable you might consider demonstrating the pixelation tool for each of the 3 steps in the activity guide rather than having students watch the tutorial video.
Computer screens emit light, so when you mix RGB colors, you are really mixing light together. This is counterintuitive for many students who have grown up mixing paints in school. When you mix paint it absorbs light.By iLKke. Apparently pixel art is cool once again, and if you are reading this blog, chances are, you like pixel art. There are many ways to go about pushing pixels, and this is just one of them.
Sadly, this tutorial will not teach you how to draw or come up with nice ideas, sorry. Also I will not go into program-specific details, you need to have some basic familiarity with the software you want to use. What to do: Using black colour, make a little drawing inside the bounds.
If you start with a bad drawing, no amount of polish will be able to save you. What to do: Colour inside your drawing, just set the basic colours and avoid any shading Important: Make sure your base colors work well together and are also bright and vivid enough, at this stage the drawing should be even more readable than the last stage, not less.
What to do: For each of the base colours from the previous step, make one darker color and use it to add shadows where needed. What to do: Add some colour to your black outlines.
Add as many new colours as you need. Important: One neat trick is to use outline colour to imply shading as well. Hopefully your little sprite will end up looking like a tiny toy. If it looks terrible try to figure out where you went wrong.
Perhaps you were too ambitious and wanted to put too much detail into such small space? Keep in mind that it is always good to simplify the shapes and focus on giving them volume. Perhaps you are just hopeless and the more you work on it, the worse it looks? In that case there is only one thing to do: take a break and feast your eyes on some good pixel art until you regain your vigor. Conveniently enough, here are some more sprites one of which is the new favicon for this site all made using the delicious recipe described above.

Wish to see more beginner tutorials, I always appreciated your work. Nice one — thanks. Got any hints about making seamless tiles btw? Besides keeping the making a one colored border. Thanks so much for this! Maybe you would be willing to make one on drawing and animating characters in the same format too? For shadows, more than one shade is used in the example.

I've tried to get into coding but I never had a goal to work to. Now I finally found something I want to build: a program that converts a image that you can draw yourself into a binary code. I've made a simple start; a drawing program with erasing tool that draws a black line on white. I need to find a way to make it bigger without changing resolution. I made another interpretation of what a bitImage could mean by using a long instead of a double array of booleans.
A long has 64 bits which means it can represent an 8 x 8 image of bits. This is probably more in the spirit of what your friend was talking about:. As an example of why this is more like what your friend was talking about, here is a sketch that makes a random bit image and left shifts the image every time the mouse is pressed:.
