...although it may just be a mistake in the documentation - but it took me surprisingly long to find that out.

From the documentation of E.HSBtoRGB, you might be tempted to write
```
    let Color = E.HSBtoRGB(i/Steps,1,1, true);
    g.setColor(Color[0],Color[1],Color[2]);
```
but this is wrong! You have to write
```
    let Color = E.HSBtoRGB(i/Steps,1,1, true);
    g.setColor(Color[0]/255,Color[1]/255,Color[2]/255);
```
instead in order to get the expected results!

(Please note: you cannot simply write
```
    let Color = E.HSBtoRGB(i/Steps,1,1);
    g.setColor(Color);
```
as the Bangle.js 2 does not support 24-bit color)

(see GitHub for some examples)

Thanks - yes, it's a bit frustrating. I was considering adding the option to output as 16 bit, or maybe just building it into the Graphics instance.

Formatting Help

Don't worry about formatting, just type in the text and we'll take care of making sense of it. We will auto-convert links, and if you put asterisks around words we will make them bold.

Tips:

Create headers by underlining text with ==== or ----

To *italicise* text put one asterisk each side of the word

To **bold** text put two asterisks each side of the word

Embed images by entering:
![](https://www.google.co.uk/images/srpr/logo4w.png)
That's the hard one: exclamation, square brackets and then the URL to the image in brackets.

* Create lists by starting lines with asterisks

1. Create numbered lists by starting lines with a number and a dot

For syntax highlighting, surround the code block with three backticks:

```

Just like Github, a blank line must precede a code block.

If you upload more than 5 files we will display all attachments as thumbnails.
