1. Answer: The high contrast of complementary colors creates a vibrant look especially when used at full saturation. This color scheme must be managed well so it is not jarring.

Complementary colors are tricky to use in large doses, but work well when you want something to stand out. Analogous color schemes use colors that are next to each other on the color wheel. They usually match well and create serene and comfortable designs. Analogous color schemes are often found in nature and are harmonious and pleasing to the eye.

 

2. Answer: The Triadic color scheme is aptly named as it consists of three colors that are spaced evenly around the color wheel; when the colors are linked by a straight line, they form a triangle. The third color is used (along with black, white or gray) as an accent. Triad. A triadic color scheme uses colorsthat are evenly spaced around the color wheel.

 

 

3. Answer: the three most common color models in digital media. The three most common color models are RGB, CMYK, and HSB

4. Answer: RGB (red, green, and blue) RGB (red, green, and blue) refers to a system for representing the colors to be used on a computer display. Red, green, and blue can be combined in various proportions to obtain any color in the visible spectrum. Levels of R, G, and B can each range from 0 to 100 percent of full intensity.

5. Answer: determines how the components of a color are combined, based on the number of color channels in the color model. Color modes include grayscale, RGB, and CMYK, among others. Photoshop Elements supports bitmap, grayscale, indexed, and RGB color modes.

 

 

6. Answer: The phrase "out of gamut" refers to a range of colors that cannot be reproduced within the CMYK color space used for commercial printing. Graphics software is designed to work with images in the RGB color space throughout the editing process.

7. Answer: RGB stands for the colors red, green, and blue, the colors widely recognized in design fields as the primary colors. The RGB model is known as an additive model, where colors are added together to make up what we see on the screen. Basically, pixels on a television set or computer monitor create tiny pixels that, if viewed under a magnifying glass, are one of those three colors. Light is projected through them, blending the colors on the eye’s retina to create the desired colors.

CMYK, on the other hand, stands for the colors cyan, magenta, yellow, and black. CMYK is a subtractive model. This gets a bit complicated, but the idea with subtractive models like CMYK is that colors from the spectrum are subtracted from natural white light into pigments or dyes. These pigments, then, are printed onto paper in tiny little cyan, magenta, yellow, and black dots. If you were to take a magnifying glass to a magazine cover, for example, you would see that the main image is really just a bunch of dots spread out, some closer than others, to appear like the colors we want.

8. Answer: Adobe Color is integrated right within Illustrator and lets you create, save, and access your color themes. You can also explore the many public color themes available on Adobe Color and filter them in several ways: Most Popular, Most Used, Random, themes you've published, or themes you've appreciated in the past.

9. Answer: HSL and HSV(also refer as HSB) are both cylindrical geometries (fig. 2), with hue, their angular dimension, starting at the red primary at 0°, passing through the green primary at 120° and the blue primary at 240°, and then wrapping back to red at 360°. In each geometry, the central vertical axis comprises the neutralachromatic, or gray colors, ranging from black at lightness 0 or value 0, the bottom, to white at lightness 1 or value 1, the top.

10. Answer: Red can boost your energy, yellow often makes people feel happier, and blue is proven to bring down blood pressure and slow your heart rate which is why it is often associated with being relaxing. If you combine the happiness of yellow and the relaxing feel of blue you get green, a very pleasing colour for many people.

 

2. Use image editing software to create a new document that is the default size. Draw a variety of six shapes on your documents. They can be different shapes and sizes. Use a color theme, as discussed in the textbook, to fill each shape. Label the image with an explanation of your theme. Save as 5_Apply_themes. LO 5.4
