RGB value

[srg]

Hi, I wonder if it is possible in AP to change colors controlling the value of RGB. Thanks

[RichardMH]

Your request is a bit vague. But if I've interpreted it correctly, yes. Can even do Hex if you are that way inclined.

and how you do it. What I mean is, when I want to modulate the colors in a photo using for example the selective color adjustment or the HSL adjustment , I move the various slider and check the result; I am wondering is moving the individual sliders or in any other way could be possible to see the resultant RGB value.

If you want to see the rgb value, use Info. I have it on the bottom right.

To elaborate...

You can drag a sampler from the Info Panel to anywhere on the photo and that will show you the RGB value at that point

Changing the sliders in the "selective color adjustment or the HSL adjustment" will update those RGB values in the Info Panel

Other than that, I'm not entirely sure what you are wanting to do exactly

Thank you. But when I change the sliders the value of RGB do not change. What am I doing wrong?

The info panel only updates after you lift the mouse button from the slider.

it will not update while you move the slider.

So I would suggest to reformulate the feature request:

* Please adjust the info panel to update immediately even while dragging sliders in adjustment layers.

I'm wondering for what purpose you want the value while still moving the sliders (the underlaying use case).

Do you want to achieve a specific RGB value for specific areas (1 pixel)?

It is possible by workarounds, e.g. adding a vector shape in the target color, blend mode difference. It will become black (real time) when you get the perfect match between the target color and the lower layers. Using a levels adjustment on top (clipped by a copy of that collared rectangle shape), and setting white level to e.g. 10% will boost the indicator for fine-tuning.

If you want to know if the current color is below or above the target value, use a copy of the indicator layers, but change blend mode to subtract.

If both indicators show the same color, you are below target color. if they differ, you are above target color.

Your RGB values are changing in the video

You dont need to lift the mouse on Windows

Interesting, good news, Thanks! – How about the Histogram Panel? There I also find it disturbing if changes sometimes don't live-update but rather seem to require to press the yellow warning triangle to get updated (although this button is for 'fine' details only, according to its tooltip). Do you experience such a limitation with histogram updates in Windows? Unfortunately I couldn't detect the conditions yet that cause this behaviour.

Only after letting go the sliders

Histogram is partially broken on all platforms, and never got fully fixed:

• missing histogram in adjustment layers on iPad
• histogram and scope freezing after some random time (Desktop frequently / iPad occasionally)
• Need to to get an update

for many workflows histogram is essential requirement. Not getting real-time updates is painful.

too complicated for me, but thanks
