Color utilities component

Kodular makes it possible to use hexcolors when you choose a color. Internally this color is saved as an integer.

In the designer it looks like in the textbox but when i use the convert in to Hex block and want to convert the integer to hex it displays the transparant bit in the front instead of the back.

And when i use the convert hex to int block it expects # in front of the hex.

So i guess it should be one way or the other. FF in front or FF in the back. This way it is confusing, at least to me. :crazy_face:

Color Utilities giving wrong results

There exist few possible hex values for the same thing.
As you know the ‘FF’ in this case is the value for alpha.

Not sure why app inventor uses a other type of hex values.
Same for the color picker by vishwas.
(I still dont understand why we dont use the correct type for hex numbers…)

I created the component and I choosed the (correct <- for me) way.
Because in almost all other places in the world you can find the first two letters of a hex value are for the alpha of a color.

Browsers use the rgb + alpha format while rendering colours. That means, for the colour picker previews to work, we have to put alpha last.

I guess in Kodular there should be one way. So alpha in the front or alpha in the back, not both ways in one platform.

Sticking to AI standards is probably the best way to go
(Even with other stuff like array indices starting from 1)
