I need to get an all black pen color and I was wondering if it would work if I could use RGB values. Or you could just show me how to get a plain black pen color. Thanks!

cool! thanks!

Hey! Using your help, I made a pen logo! I haven't shared it, but you can check it out on phosphorus: https://phosphorus.github.io/#140520107

R = Red
G = Green
B = Blue

Color = (R * 65536) + (G * 255) + B

R , G and B should be from 0 to 255 inclusively.

The RGB for Black is (0,0,0) or just 0 if we do the formula up here.

For RGB colours in general you have to do this for decimal RGB values (0-255):

set pen color to (((r :: #ff0000) * (65536)) + (((g :: #00ff00) * (256)) + (b :: #0000ff)))

or this for hex codes:

set pen color to (join [0x] [000000]) // 0x makes Scratch interpret the string as a hex number

set pen color to ((0) / (0))

To get a black color.

Just to note that the value multiplying the G should be 256, not 255.

You also should ensure R and G are integers (otherwise it'll ‘bleed’ into the lower components when multiplied by 65536 and 256)…
[Doesn't matter about B being an integer, since it can't bleed into anything lower. It'll only take the integer part of B anyway.]

Also, you can make the pen semi-transparent by setting the alpha component:

A*16777216 + R*65536 + G*256 + B

The alpha value, A, should also be an integer from zero to 255. A value of 255 means fully opaque while a value of one means pretty much totally transparent. Note that an alpha value of zero is considered to be fully opaque, in order to make everything backward compatible with earlier versions of Scratch that did not recognise the alpha component.

Thanks, I needed that info.

if i want to color something on pen from a rainbow pallete and move the sprit of tthe pen to a random place how do i get the color it is on without a million touching colorblocks?

You could use the pen's brightness value and set it to the minimum

just

set pen color to [#000000]

What about costumes? How do you change the color of a costume using hex code?
