Creating muted pastel like tones in lightroom

Been trying to figure out how to edit raw files to have this muted pastel like look for the longest time (so far have not come close). Is this possible in Lightroom or is this more complicated color grading requiring Photoshop? Any pointers would be appreciated!

I'm going to say that is first a matter of the camera light balance being set for cloud but being actually lit by skylight (no sun) being filled by reflected light from concrete. There might have been some desaturation done in edit.

This 100% can be accomplished in Lightroom. There isn't a single global adjustment that will get you where you want to be, you have to play around with the HSL sliders for each color. Personally, I've found that the decreasing highlights, lifting shadows, and mildly lifting blacks is a good way to begin. You are basically reducing contrast. Beyond that, you can try using the HSL sliders to desaturate any dominant colors and bump up their luminance. Be gentle with the HSL sliders. Lastly, I have used the tone curve to add a very subtle amount color (usually blue to the shadows and magenta to the highlights0 depending on the scene, but I think focusing on the exposure and saturation tweaks will give you the most bang for your buck.
