I think it really depends on what you are correcting.
From my research as I have been working on lighting in my garage and spot lighting recently - for dark colours you want colder lighting i.e. 5000-6000K+, for light colours you want warmer lighting i.e. 3000K- 4000K (The higher temp and higher lumens sometimes can wash out those lighter colours like a light metalic silver I find and make it difficult to spot defects).
My overhead garage lighting is 10,000 lumens total and 5000K temp. I plan on adding around 10,000 to 15,000 more lumens since my garage work space is around 400 sq. ft. You generally need more lumens when covering larger areas - "100 to 150 is what is recommended for "detailed mechanical tasks" by the IES (Illuminating Engineering Society)" - again based on research on other forums. So if you have a 200 sq. ft. garage space you would want around 20,000 lumens for proper brightness in a working space.
I have a few different spot lights of different brightness and colour temps depending on the paint color I am working on - one 3000K and one 5000K which I will use to help spot defects both are probably around 1250 - 1500 lumens. I dont think you would need more than that for a spot light/ working light for looking for defects.
