Hey I've used Artstudio Pro on the iPad for quite some time and just downloaded the Mac app. I have some questions on how to use it:

1. Most importantly: Where is the color wheel? I just see some preinstalled swatches.
2. Can you customize shortcuts on the mac?
3. Can you move windows around
4. The description in the app store said it has the same features as on iOS / iPadOS, but the mac version looks significantly less "flexible" in usability so far (readjusting windows etc). Is that just my first impression?

Thanks for your help

Cool mockups! Having the luminosity lock work on the hsb sliders aka shifting saturation while brightness adjusts automatically  to preserve luminosity would be awesome!

WOW I'm so excited for this thank you!
As a user, I'm not sure how I would go about activating it judging from your screenshots of the controls there. I'd expect some kind of toggle to use in the color wheel window. But as an indicator that shows that it is currently active, the little sun icon on the wheel works well and gets the point across.

Question - do you think you will have to lock/unlock luminosity often? Or keep it locked all the time?
I’m asking because maybe a switch in Preferences is enough?

Thanks for asking and making sure! Having it in the preferences wouldn't help, as it needs to be directly connected to the hsb color shifter. You need to be able to see how it changes the color if switched on  and immediately switch it off if need be, to maintain a continuous workflow while painting. Long story short: Yes, it's going to be used often.

An interesting detail in both the magic picker and infinite painter implementations is that when you change the hue, it actually does adjust both saturation and value to maintain the "perceptual" value. You can see that is happening because the reticle in the hue/value square auto-moves on both axes. (it can be seen happening in the vid I linked.)

Wouldn’t that mean when you turn the image to black and white, the values are still different? Bc the whole point of the luminosity lock, in contrast to what you described, is to keep the exact same value while shifting hues. That is to take chroma into account while painting, so you don’t mess with your contrasts. In the video you posted it looks like the values don’t actually stay the same, although I didn’t quite understand what the toggle does exactly from how it was explained. But I think the effect wouldn’t be the same, making it a different feature?

I’d like to revive this topic. It would be amazing to have this feature in Artstudio Pro for iPad. It’s already there in the brush settings, so please please please reconsider implementing it in the hsb color shifter. It would allow me to pick another color while maintaining value - making sure I don’t mess with contrasts while working. It would make my life so much easier to have this.

Here’s a short video on this feature made in Photoshop with the Coolorus Plugin. https://vimeo.com/93007724
