I was looking at a web page listing specific colors and it had a spot next to each color listing a Hexadecimal. What the hex is a Hexadecimal? I did google it but have math dyslexia (dyscalculia) so had trouble understanding. Grazie.

We use base 10 for counting. we add a new digit to a number every 10 numbers. at 10 we add the ten’s place. At 100 we add the 100’s place.
Hexadecimal is base 16. It has 16 values in the 1’s place (1,2,3,4,5,6,7,8,9,A,B,C,D,E,F) and then we add another digit.
F in hexidecimal is 15. 10 is 16.
This numbering system exists because computers are built around switches that can take on 2 states. If you use 4 switches they can take on 16 states.
