Hexcodle #321

It's mostly practice in the rgb color space and understanding hex codes. I start with the first digit for each of red, green, and blue, like in the Hexcodle Mini. Then I insert the second digit for each, and if I don't have a good idea then I'll go with 7 or 8.

If the color is dark, the first digits (the R, G, and B in #RXGXBX) are more likely to be less than 8. If the color is light, the first digits are more likely to be more than 8.

The hex code help link on the game's page is pretty helpful - https://www.freecodecamp.org/news/how-hex-code-colors-work-how-to-choose-colors-without-a-color-picker/

For the first digits, I make a guess, for the second digits, I choose 7 or 8, basically using a divide and conquer approach.
