How do I get a consistent colour?

[WoZZeR]

Hi chaps

I am struggling with obtaining a consistant colour balance indoors using a purple background during close up photography.

I am using ambient light (natural daylight) and no artificial lighting at all.

So, the camera is a Canon 5D II, the lenses either 70-200 F4L or 24-105 F4L depending on subject.

I mostly use Aperture priority and have tried using Custom White balance with a photograph of a sheet of paper as the reference.

Somewhere along the line I must be missing something very simple, If I take 4 or 5 consective photographs but of very similar but different subjects I get 4 or 5 different shades of purple as the background.

I am getting a bid fed up trying to correct it all the time on the PC.

Any of you more experienced and knowledgeable chaps able to point to me in the right direction.

Cheers

Warren

Thanks for the replies chaps

I shall have a go using Manual, Auto White Balance and RAW in the morning and see what happens.

My usual photography takes place outdoors so this is a whole new area for me. Flash would add another layer of complexity for me to grapple with.

The Colour Checker looks interesting and it just so happens we got Amazon Vouchers from work last week as a thank you for not getting or dying of Covid 19.

What type of subject are you lighting?

Mostly small plants, it's not critical to get the colour absolutely spot on but close would be nice.

My first results using RAW (I haven't used it for ages) and Manual Mode are looking more consistant. I also switched Picture Style to Standard (It was on neutral) and Auto Lighting Optimiser down to Low in the Custom Functions.
