Label HTML color code

[Theo_Jansen]

Hi,
I have adopted the code from Anke to make a color in Html with labels.

It works directly with a color and a number. I was trying it with "make color" but this seems not to work. Is that right or do I miss something?

Could anyone help me with this.

I was trying it with "make color"

Is this what you tried?

might work if you replace the color icons with the make color Block.

If not working, what did you try?

I am surprised that it worked at all

Does AI2 coerce some color blocks into text color names when you force them through a text JOIN?

Must try this with Do It on the JOIN when I get online.

[Theo_Jansen]

I tried this

It gives black. It should be red....

I am not sure if the label html can interpret the decimal64bit colour numbers. It should accept a hex colour value

[Theo_Jansen]

Do you mean that this is not the same?

I do mean that

[Theo_Jansen]

aha... I thought it is the same because the set label text color accepts both...
Can this be simple converted?

[TIMAI2]

If you just want some custom colours try these tables:

METRIC RAT AI2 - ANDROID and HTML Colour Codes

you will want the hex codes (e.g. #FF0000)

[Theo_Jansen]

Thanks, this a nice overview. I rather have a procedure that converts it because I work already with this code in my app.

[SteveJG]

Do you have

set to HTMLFormat? A long shot but setting HTMLFormat in the Label Properties might allow your original concept to work.

[Theo_Jansen]

Yes I have set this. The code is not displayd

[Theo_Jansen]

this works. I know it is ugly, but I wanted to know if this works

[Theo_Jansen]

Sorry this is a stupid solution.....

Do you know how is the color code is named that returns the "make color"?

[Theo_Jansen]

Is that the decimal 64 bit?

[SteveJG]

make color is RGB.

make color

make color takes in a list of 3 or 4 numbers. These numbers in this list represent values in an RGB code. RGB codes are used to make colors on the Internet. An RGB color chart is available here. This first number in this list represents the R value of the code. The second represents the G. The third represents the B. The fourth value is optional and represents the alpha value or how saturated the color is. The default alpha value is 100. Experiment with different values and see how the colors change using this block.
