 I have a template if you're one of my students in Doc Sharing.
I want you to open it, this it.
it says Transparency Template
click this little icon down here for a new layer
We're going to call this one swatches
You're going to put a sample of each color that you use here
The hexadecimal the RGB and the CMYK numbers 
beside this swatch
The next layer you can name it or not name it
It's going to have a color
I'm going to get a magenta pink
I'm going to draw with the marquis tool
A rectangle okay
I'm going to go to edit fill
Make sure you have for ground color blend mode normal 
opacity a hundred percent and do not have was
preserve transparency checked.
Click okay and now we filled out one
 Since we're in the marquee tool
We can just move this over
Now I want to make a new layer because I have to 
change the opacity
I have to have a new layer for the new color I pick
I'm going to go in here and pick maybe a cyan type tint
OK there's a cyan type tint.
I'm going to to go to edit fill all the things are set.
  Okay now
select deselect change the opacity
 Where are our three colors
You can make little squares which is what I do,
If you're not that familiar with Photoshop just go to the eye dropper
one on the left and paint a swatch
on the swatches layer
And then get the eyedropper again
and get the middle one
now we're still on swatches, get the paint brush
and paint here, I'm just trying to make it easy for someone that might not know Photoshop.
and then get the eyedropper and get this color.
and go back to the paint brush and paint here.
You've got your 3 swatches
I'm just going to go to black and white.
You're going to go to the top layer (actually the swatches layer).
You're going to get your eyedropper and pick this one.
and go to black and white again sorry.
oh no no no I'm mistaken
 click and get the numbers now
So I would write the numbers down I wasn't when I
was recording it before but I would now
Copying the hexadecimal which is down here
Command C or control C
And then copying the RGB
 235  25  237
And then the cmyk  30 83  0  0
So then I'm going to click OK
Now I'm going to go to black and white
Go to the type tool and click
I still have in my buffer the hexidecimal number
I have a very fancy type, I might just change it.
There's a type there's the hexadecimal
Here and type in the RGB
Because RGB is three numbers
235  25  and 237 
There are 360 on the color wheel, that's a whole different conversation.
click the check mark
The click here 30  83 and 0  0
they should be separate
cyan magenta yellow and black
it's subtractive color
It's not from light it's usually for inks and dyes
So the next color I'm going to pick is the purple
I'm going to take it from here I think it will be more accurate
It's already highlighted hexadecimal
Command C
I'm going to write down 151  R   98 G   240 for B
57 for C 68 for Magenta then 0  0  
I'm going to click OK
Oh I don't have to be on swatches, I'm sorry
Get black and white again get the T for type
paste, check mark
click again
RGB numbers which is additivie color form light
like your monitor, your TV
and then
click check mark, and then click for cmyk
57 space 68 space and then 0 and 0
then click the check mark and we only have one more to go. 
on this one, I'm going to click here and copy the hexidecimal
copy the hexidecimal
and then write down R 161  G 215 B 249
and then C  33 Magenta 3 Yellow  0  Black (K)  0 "K is Black"
and I'm going to click cancel because I really don't need it.
Go to black and white and get the T
paste your hexidecimal
go to the check mark
you're still in the type tool  type in 161  215 249 and then I'm going to check mark.
and then I'm going to type in the cmyk
33  3  0  0
so essentiallly
there is one homework assignment
however if you look at what I've shown you in your eCompanion
I have this one
I don't care if you have paint swatches or squares
In this one it's more complex
challenge yourself with one of them at least
and you know how I grade, 2 examples is the minimum
but if you want to get an A you might want to do one or 2 more.😜
So there you have it.
oops there's the screen
and there you have the Transparency and you saw the Richard Mehl
the guy from Visual Arts in New York
he talked about it 
Albers, Josef Albers explored this
so that's your homework.
And if you're not in my class there you have it.
