Deciding factors when Color grading in LR
Hi everyone, been into photography & LR for a couple of years. I'm loving this hobby and feel I've progressed in many ways, but I find color grading really, really hard and will much appreciate any feedback I can get on the process itself, especially deciding factors while color grading. Sorry for lenght of post, not sure how to properly explain my challenges without being detailed.
I've bought courses and spent so many hours on youtube videos and reading various posts. I understand all the basics and I am well familiar with color theory. My practical issues are eye-balling and figure out which color tweaks this particular photo needs and that I am partially color blind. Partially, as in sometimes certain colors can be a bit hard to differ, and then there's the insecurity of knowing a color grading I think looks great, and which looks a certain way to my eyes, might look slightly different to others (or not good at all).
Let me take a practical example and try to explain my issues & thought process:
I'm sitting down with a photo taken on a bridge with clear leading line towards an orange sky/sunset, do my basic edits and then it's time to figure out where to go with colors. I have a lot of blues in the photo and there's a lot of warm orange from the sunset, so a blue/orange complementary split seems natural:
- Dominant color: One of them should be the dominant color, but what are the things I should consider when picking the dominant color?
- Color HUEs & creating harmony: Then there's finding the exact HUE of my blues & oranges that go well together. If I had more experience I could probably eyeball it but right now I constantly feel uncertain. I may check the HUE of my colors using LR picker, or I can export & upload to color.adobe.com and check color wheel values (and i.e. do the same with a reference photo grading I like), but this doesn't take relative color and the context into consideration (which colors they combine with, or what the color actually looks like in combination with other colors). So I feel eyeballing and picking what looks good is the only real option, but there must be some "rule of thumb" to when I've reached color harmony & how to get there. Or what are the deciding factors to consider when deciding if I i.e. should shift my oranges towards red or yellow
- Color contrast: I realize there ideally should be a clear separation between colors, but again - what are the deciding factors to figure out when I have a good color contrast/separation, or are there general tips to get good color contrast? Both between different colors and warm/cool tones
- Luminance: So I want to go for a moody, dark look and I've shifted my blues to where I think they look good, then I'm sitting here for the next hour shifting my oranges and yellow luminance up and down for 100+ times, trying to decide. Again, what are the things I should take into consideration when deciding? Something feels off but I can't figure out what
- Spiking a feeling in the viewer with color: So we know warm colors may evoke feelings like happiness & energy, cool colors may evoke feelings like calmness or sadness. Then again I'm wondering what the deciding factors are when there's more than one color
Etc etc etc. Sometimes I nail a color grading and I get results I am pleased with, but most of the time the whole process is really draining, consists of a lot of confusion and I give up editing an otherwise good photo cause I can't nail a color grading I am happy with.
I somehow need to learn the best order of doing my grading and the basic deciding factors during the grading process. Deciding factors both from the beginning, when I sit down and figure out where I want to take my grading, and during the grading process (what to be aware of, how one change impacts another, etc).
All input will be much appreciated. Tips based on what I explain, posts, valuable youtube videos on the subject - anything. I am so fed up and wasting so much time being stuck in color grading it's getting quite demotivating. In advance, thank you
