Here is my latest rendition of the first photo



Most of the adjustments were done in LightRoom Color Grading and shifting highlights, midtones, and shadows away from the red toward Hue 160 to varying degrees.

The Photoshop video tutorial was instructive, but left me with a very dark image.

Cheers... Brian

def. away from red! turned green now (into opposite/complementary colours). ;)
tricky indeed, these major adjustments. IMHO it already looks much better.

for what it's worth, again- if you want to change the light, PS adjustment layers c/b a great help.
layers > new adjustment layer > curves. mode has to be 'lighting', the last option on the drop-down menu.
curve will appear. default setting RGB, adjusting separate colour channels (only) an option. on the left the eye droppers with a little hand on top.
clicking on the hand symbol, then hoovering over the image, will reveal the position of any area on the curve. when you click on an area in the photo, a control point will appear on the curve. that you can drag above/beneath the line to brighten/darken that particular area.

tried to find you some links -in proper english ;) -
https://digital-photography-school.com/how-to-do-quick-and-easy-curves-adjustments-in-photoshop/

https://helpx.adobe.com/photoshop/using/curves-adjustment.html
https://helpx.adobe.com/photoshop/how-to/lighten-darken-photos-with-curves.html or dodge & burn
(for iPad? )

PS? when adjusting colours while using curves, the mode has to be set to colour (or selective colour). using the default adjustment layer > curves, adjustments will affect e-ve-ry-thing, colours as well as lighting.
same goes for all colours in the RGB colour mode. you can select red, green and blue from the (RGB) drop-down menu and use the slider > particular colour to complementary colour.
