NUMBERS AND COLOURS

Today we talked about colours and numbers in photoshop.The numbers are the same as binary code but in bainary code the number sterts at 1,2,4,8, and 16 but in photoshop it is 1 and 16 and 255 but we dont wright that, we just start writing from 1 and 16.When we start writing 1,2,3,4,5,6,7,8,9 under 1 we dont write 10 under 1 we write A,B,C,D,E, and F just up to F.A= 10, B=11, C=12, D=13, E=14 and F=15.If you want to write like 16, write 1 under 16 and 0 under 1 which means 1*16, and 0*1 which = to 16.If you want to write 256, you have to write F under 16 and and 0 under 1.RGB stands for Red,Green, and Blue it should go in this order always.If you want to get pure red, you have to type FF for red , 00 for green and 00 for blue.If you want gray colour you should write A0,Ao,A0 for all of them.
