Re: make grouped columns more distinctthe column color could also be used to highlight columns of larger interest - like illustrated here:

Re: make columns more distinctYes, colors for column headers!
@Holger For now, try the scroll-lock for a few important columns to keep them pinned to the left edge of the grid.
Re: make columns more distinctThanks for the suggestion @Holger . We are investigating the feasibility of this feature request and if it something we will pursue.

Suggestions for new features to aid in better table organization
Re: make columns more distinctOur development team is looking into this and we may be adding this as a new feature in upcoming versions of JMP.
Re: make columns more distinctThanks a lot 
Besides highlighting columns in the column list on the left, platforms could also benefit if Filter Col Selectors and Col List Boxes will share the same color coding.

Re: make columns more distinctThis wish also focuses on having a better organization of columns, not by color but by hierarchy.

In general, working with several columns in JMP, common in manufacturing data, is really challenging.
Re: make columns more distinct+1 for column header colors.
Re: make columns more distinctI can confirm that column header colors are under active development for the next major release of JMP (JMP 18).
Re: make columns more distinctthanks a lot.
same for Filter Col Selectors and Col List Boxes?
Re: make columns more distinctThank you - delivered with Jmp 18
:)
Re: make columns more distinctThanks to Jmp Development for making this feature available in Jmp 18 - really cool.
It got so easy now to pick the right column in platforms 
In Angling, Wrangling, and Untangling Data @ 1:03h @julian gives a short introduction on how to use the new feature:

make columns more distinct (:corazón_verde:)☐ cool new feature
☑ could help many users!
☐ removes a „bug“
☐ nice to have
☐ nobody needs it
sometimes it's hard to find the right column again and again.
some suggestions to make it easier:

- define special colors for special columns (or groups):

- make the vertical line between groups thicker

How is this new feature accessed in JMP 18? I see a reference to a video, but I don't see a link to it. If someone could provide a pointer to the video, that would be great.
Thanks in advance,

Re: make columns more distinctright click - and change the color:

Re: make columns more distinctThank you @hogi !
Re: make columns more distinct (:corazón_verde:)Hello,
Is there a way to color the column headers using JSL?
I have looked through the functions but couldn’t find an answer.
I know there is the command to color the cells, but is there an equivalent command to change the header background color, like the right-click > Header Background Color option?
Column("TEST") << Color Cells("Light Blue")
Thank you!
Re: make columns more distinct (:corazón_verde:)good question.
col << Set Header Background Color( "Red" );
col << Set Header Text Color( "Magenta" );
surprisingly, the setting is not saved via Copy Column and not saved via Save Table Script.
Re: make columns more distinct (:corazón_verde:)In JMP19, Column Tags are added.
They are much more versatile than the color coding of the headers.
extremely helpful!
Re: make columns more distinct (:green_heart:)Thank you for your helpful answers, @hogi !
Best,
