Problem with RGB color on 3D

im having kinda of a problem on unity, so i want to get a RGB color exactly as it is, but because of lighting and maybe other things it’s not matching, but for my project i need the colors to match exactly without difference i’ve tried many things, but still it won’t give me the exact color.

Now maybe this is not possible in 3D, which my last option is to make on 2D…

(Im using color32 struct to change the color of the material, i’ve also tried changing the light color same to the RGB but still not gonna give me the correct. If you have a solution shadows don’t matter or anything like that all i need is to get the color correct as on rgb with no difference ) (Building on WebGL)

try to use Unlit material
