an RGB value

3. Answer the following RGB (color) related questions: a. What is an RGB value?

b. What color does an RGB value of (128, 13, 255) represent in Excel?
c. How many different colors could be represented with an RGB scheme if only 3 bits were

used to represent each RGB component (3 for R, 3 for G, 3 for B)?

What is the color depth of an image using this RGB configuration?
d. How many different colors could be represented with an RGB scheme if 8 bits were used

to represent each RGB component (8 for R, 8 for G, 8 for B)? What is the color depth of an image using this RGB configuration?

 

4. The R&D group is testing an alternative color scheme to RGB labeled RGBO where an additional color component (Orange) is added to the traditional Red, Green, and Blue components in order to specify a unique color.

  1. How many different colors could be represented with an RGBO scheme if 7 bits were used to represent each RGBO component (7 for R, 7 for G, 7 for B, and 7 for O)?
  2. How many different colors could be represented with an RGBO scheme if 8 bits were used to represent each RGBO component (8 for R, 8 for G, 8 for B, and 8 for O)?
  3. Finally, how many different colors could be represented with an RGBO scheme with 4 bits for Red, 8 bits for Green, 9 bits for Blue, and 10 bits for Orange?

5. Create an image of your own in Excel, similar to smiley:

  1. Your grid should be 15 x 15. (What is the image resolution for this?)
  2. You need to use 6 colors. (What is the color depth for this?)
  3. Calculate the storage size required for your image, assuming the usage of a full bitmap, with 32-bit representation of colors. Give the answer in bits and in bytes.

6. In the Day04 homework folder, we have included an Excel file named Day04HW_Icon.xlsx that contains a bitmap image of the latest popular cartoon characters. Given an RGB color scheme where an individual color in the full bitmap uses 5 bits for the Red component, 4 bits for the Green component, and 6 bits for the Blue component:

  1. What is the resolution of this image?
  2. What is the color depth of this image?
  3. Calculate the storage size required for the full bitmap of this image. Give the answer in bits and bytes.

7. We have discussed a variety of different ways that a series of 0s and 1s can be interpreted by a computer. Given the following 7-bit binary data stream, what are all the possible data values that this data could represent?

1001100
(Two possibilities include -12 and 76)
