## The challenge#

When working with color values it can sometimes be useful to extract the individual red, green, and blue (RGB) component values for a color. Implement a function that meets these requirements:

• Accepts a case-insensitive hexadecimal color string as its parameter (ex. `"#FF9933"` or `"#ff9933"`)
• Returns a Map<String, int> with the structure `{r: 255, g: 153, b: 51}` where rg, and b range from 0 through 255

Note: your implementation does not need to support the shorthand form of hexadecimal notation (ie `"#FFF"`)

Example:

``````"#FF9933" --> {r: 255, g: 153, b: 51}
``````

## The solution in Python code#

Option 1:

``````def hex_string_to_RGB(s):
return {i:int(s[j:j+2],16) for i,j in zip('rgb',[1,3,5])}
``````

Option 2:

``````def hex_string_to_RGB(hex_string):
r = int(hex_string[1:3], 16)
g = int(hex_string[3:5], 16)
b = int(hex_string[5:7], 16)
return {'r': r, 'g': g, 'b': b}
``````

Option 3:

``````from PIL import ImageColor
def hex_string_to_RGB(hex_string):
rgb = ImageColor.getrgb(hex_string)
res = {
'r': rgb[0],
'g': rgb[1],
'b': rgb[2]
}
return res
``````
