Yes please. This is one of those where I am just baffled that it hasn't been addressed yet. How hard could it be?
I literally never ever use RGB sliders.

Oooh a merging of threads. Still wanting this very much!

*watches this space*

Adobe team, there are many requests for the ability to set and lock a default color mode, particularly HSB. These many requests are scattered across the uservoice forum with different terminology in turn lowering the collective vote weight.

This is an essential feature. I, and many other users change the sliders to HSB hundreds of time a day. Can you help us? ...... can you respond....?

I never want to see an RGB slider ever again in my life.

There are many similar requests with different titles. @adobe: how do we combine the same but differently worded requests into one mega request? The votes would add up.

Please do this.

How about just making User Defined Workspaces so I can set things up the way I like them ONCE, then save it and never have to think about it again?

ALSO

Can you please make "persistent" brush libraries ACTUALLY persistent?

AND

It would be cool if I could direct Illustrator to my user-defined files in a single folder OUTSIDE of your application folder, so I don't have to constantly reinstall my stuff when you release a new version.

You KNOW what needs to be done. Take an interest in something other than subscription fees.

Well said Aleksei. Thanks for adding your voice to the thread.

Ok, I'll comment here just to attract more attention to the case.
Because RGB is really annoying and counter-intuitive. It's a programmatic value provided by coders, but unusable by people.

I agree with keith-o below. I think it's worth everyone upvoting all of the posts on this topic.

Im a pro in a large design business. I have absolutely no need for RGB sliders in any web or print situation. I would like an option to configure AI so that all color sliders can be set to HSB permanently. I never want to see RGB sliders again.

How can we pull the all the scattered posts/requests + votes into one strong message?

Personally, I would like the preference option to replace all RGB sliders with HSB. I would like to be able to configure AI so that I never see RGB sliders ever again.

I use Adobe Illustrator since 1991. I use to work with HSB color picker and EVERY TIME I NEED TO SWITCH IT BACK, because it automatically switches back to rgb. LEAVE THE COLOR PICKER WHERE I LEFT IT, ITS ANNOYING AS **** AND SLOWS ME DOWN. ITS 2021, PEOPLE!

Agreed. HSB is better than RGB in every way. A normal person can't compute the RGB sliders. There is no reason to use RGB as the default. Im a high level professional designer working in about 50% digital and 50% print but I spend 90% of my time in an RGB workspace using 90%+ HSB sliders. I never ever (0%) use RGB sliders. Come on adobe..... its 2021.

Oh heavens yes please. It's such a drag, constantly switching back to HSB again. And again. And again, with every path I just to happen to want to change.

Do vote for all the other requests on this exact same thing!

Agree with everyone. Illustrator should remember color modes AND the hex box should be universal. When will this finally be fixed?

2 years later... yep.

This still matters as much as ever.

These threads all agree with this one:

Agreed! This would be extremely helpful. RBG colorspace should allow a global HSB option for all swatches. HSB is much better and most of us think in those terms. It would improve my workflow as well.

The colour palette always switches back to the default RGB which is frustrating and disturbs workflow. I would like the ability to set a default colour slider, based on the slider you are using in your current project. I mostly use HSB.

Doesn't matter with what color pallet you work with... it should stick to whatever you choose from the top-right mini-menu option... not like it is right now that it mandatory switches back to document color mode handles

When I'm trying to edit gradient color handle (double click), and switch color mode to eg. HSB, from top-right menu, after editing the handle color again it's always switch back to document color mode specific. Example - I'm working on RGB color mode and I want to make few gradients that differ in brightness and saturation. The easiest way to manipulate the colors is with HSB handlers, so I change the edit color mode (the tooltip menu after you double click the specyfic color on the gradient bar - similar to color window) to HSB from the top-right mini-menu, but when I'm trying to edit another color on the gradient bar I get the RGB handles again, and again I have to switch to HSB which is really annoing. I think the color edit pallet should stay as I choose - same as it is in 'color window'
