I have been learning Blender recently. And I have understood that lighting plays an important role in getting the exact shade of color that we want. But I am still not clear on how to achieve this.

For ex, I am trying to create a plane for my background with the color(Hex: #ffc1c2). But no matter how much I play with the lighting(Area and point)I am unable to get this color as output in the rendered image using cycles.

Can anyone help me on how to get the color that we want as output.

The values and position of your lights (and world/HDRI) will affect the color of your object, and all the indirect lights as well, so you can't get the exact same color, except, of course, if you use an Emission node.

I've noticed though that if you delete all source of light, create a sun, reset its rotation, give it a Strength of 3.1 and an Angle of 0, you'll get the exact same color in render. So if you want to keep the exact same color you need to stay around these values, or if you play with one of these values you need to compensate with another.

If you test Emission or a sun with this precise setup but still don't get the exact same color, it may have to do with the Render settings (example: the Color Management settings, View Transform must be on Standard).

  • Thank you. It was the view transform. Playing around with raw and standard did it. – Andro Selva Aug 22 '20 at 10:22

    Except this is the worst possible solution for rendering light transport. Your dynamic range is extremely thin, and the mixtures will all skew as the three light mixture cannot be represented in the display output. Don’t do this. – troy_s Aug 22 '20 at 13:51
  • Hello Troy, are you talking about the Standard option? – moonboots Aug 22 '20 at 14:31

    Using Hex to understand color in blender is not a good place to start. https://blender.stackexchange.com/a/43503/92768 Blender works with a scene referred radiometrically linear reference space mode more info on these links: https://blender.stackexchange.com/questions/35722/when-to-use-srgb-and-when-not-to/35854#35854 and https://blender.stackexchange.com/questions/78284/white-background-with-filmic-blender – susu Aug 22 '20 at 16:55
