Question
What would part b look like?
PART B: colorArray ToCSS(colorArray)
function
This function should simply take an array of three
numbers from 0 to 255 and return a string that can
be used as a CSS color in rgb form. For example,
the input array [48, 243, 156] would return the string
"rgb(48, 243, 156)".
PART C: generateColors() function
This code should loop through each of the color
boxes from 0 to 4. It should first check the isLocked
array to find out if the box is locked. If the box is not
locked, then it should replace the current color in
the box with a new random color.
Replacing the color in a box involves a few steps.
First, you need to generate a new random color
using the pre-written function,
getRandomColorArray().
1. The background color of the entire box
defined by the div element should change to
the new color.
2. The text in the span element which displays
the RGB value string should change to
describe the new color.
3. The text color in the box defined by the div
element should be set to either black or
white depending on the brightness of the
color. This should be determined by
summing the red, green, and blue values. If
the sum is greater than 382, make the text
color black, otherwise make it white. For
example, the values in the color
"rgb(165,40,200)" add up to 405, meaning
the text color should be black.
