I don't know if this is possible, but if it is, can someone build a script that will make a sprite have effects on it that will make it the color of the hexidecimal code (like BBCode colors???) Thank you very much!

It's fairly easy to make a hex to dec converter, hopefully you know how.
Because the color effect accepts numbers through operators, drag in a + operator then another one in one of the slots.

The red value gets multiplied by 256^2, the green multiplied by 256, and all added to the blue. Does that make sense?

If you search color picker, there is a color-picker.com that shows the code.

I think he wants one in his project, so the user can enter a hex color and get a color back, or something.

Yes, that is what I am looking for. Is this possible, or is it completely impossible to do (sounds like something that would be)???

It is possible.

Hey there ScriptWriter!

This might be a bit complex, I sure don't know how to do it.

Just saying!

Yikes! I am really trying to find out how to do this.

I am going to ask for this to be moved to Help for Scripts, people who will help me there might be better at this. Even though I am an existing Scratcher, this is something I never bothered to learn how to do.

Hah… I see what you did there…

I don't really know how to do this, but I'll quote kayybee's earlier post in case you didn't see it:

I don't believe this is possible. At least, not for all colors. For instance, there does not seem to be a sprite effect that will make the sprite white.

I agree. You'll notice that when you apply a colour effect it does not change any black or white in your sprite just the colours. Infact the colour effect cycles through 200 shades before getting back to where you started. By iterating through a loop 200 times and stamping your sprite it is easy to see all the possible colours you can achieve with that sprite.

%c.sprite

1. Create a short project that will put all 200 colors on the screen in order.
2. Take a screenshot.
3. Use the eyedropper tool of a Paint program on the screenshot to find the 200 different hex codes.
4. In the project create a list of the two hundred codes with the item # corresponding to the color effect #
5. When user enters hex code, it is found in the list, then the item # used to generate the color effect.

It's not just colors, but shades which effect it, which gives it thousands of colors.

@turkey3… The RGB system with 8 bits for each color is 256x256x256 colors and includes ALL the shades and tints possible in it. In hex, of course, it is a 6-digit hexadecimal number, 2 hex digits each for R ,G, and B.

Now the way I interpreted his post was he wanted to have someone input a hex number and then have the sprite turn that color.

But SCRATCH only has 200 color effect hues, each of which can have various shades and “tints” (brightness?), right? So the first task would be to discover what the actual colors were that Scratch uses.

If it was me, I would only choose one or two fixed shades. Then there would be 400 or 600 colors total to worry about.

Once I had the hex values of those 600 colors, obtained with screenshots and a paint program (again, this is me doing it) I could take the user's hex input and match it to which of my 600 hex values was closest to his hex input, then give him the color effect he wanted.

The average person does not have sufficiently good color discrimination to distinguish accurately between so many different colors. I am sure I could shave it down even further without the user noticing any change.

I would select 33 hues and give each one two shades for a total of 99 colors… plus white for 100.

But this is all headwork. I haven't written one scrap of code to implement it. o_O

There was actually a griffpatch video that talked about this. it is this onei www.youtube.com/watch?v=aBTh756kCZw (am i allowed to post these links here???)

kind of easy:
