Custom Colour picker

[onkytonk]

Hi,
Firstly, so grateful that you’ve ported this over to iOS! Waiting on my NTAGs. Can’t wait to test it.

I just noticed something with the custom colour picker though.
The slider circles are not aligned correctly. They seem to want to slide off the screen to the left and don’t go all the way to the right. It’s like a misalignment somewhere.

Also, it would be great if I could see the colour up top when using the sliders.

Thanks again.

Thanks for the detailed feedback! I've fixed the color slider alignment issue.

What was wrong:
The sliders were using hardcoded screen width calculations (UIScreen.main.bounds.width - 96) which didn't account for actual padding and safe areas. This caused the thumb circles to misalign and slide off screen.

What was fixed:

• Replaced hardcoded width calculations with GeometryReader to get the actual available width
• Fixed thumb positioning to properly center within the slider track
• Adjusted drag gesture calculations to account for thumb size (32px)
• Sliders now work correctly on all screen sizes and orientations

About the live color preview:
Good news! The color preview at the top already updates live as you drag the sliders. Each slider change calls updateColor() which immediately updates the selectedColor shown in the preview rectangle at the top. This real-time feedback should help you dial in the exact color you want.

Additional improvements:

• Added "Clear" color preset (first in the list) for transparent/natural filament
• All RGB sliders now properly align and track your finger movement

These fixes will be included in version 1.2.0. Thanks for helping improve the app

Hey!
Thanks for all your hard work and looking forward to the update.

I’m regards to the rectangle getting updated with the sliders, I know this was already working, but if you refer to my screen shot above, with the “preset colours” in between the rectangle and the sliders, it’s very difficult to see the colour update when adjusting the sliders. Maybe it can be seen on a larger iPhone, but on my 16 pro, I can’t see the reference colour.

Be nice if the presets were moved above the rectangle, or if the presets section could be collapsed so it was easier to the reference colour when adjusting sliders.

If you really want to take it to the next level, I’ve actually been using a second app that snaps a photo, and give me a hex code of the colour it sees.

Might be pretty advanced, but a pretty cool feature if you got it working. 😊
