I honestly think that your colors aren't out of whack, I would just make sure that you're using lighting consistently throughout. Part of why he seems so pale in the first part versus the other is the choice to use hard lighting and shadow, while in the others you're using ambient lighting. Ambient lighting is great and powerful, and you can totally use it alongside panels that have hard light, but even ambient lighting has some shading to it--either with a gradient to show warm light bouncing off of the warm furniture, or darkness where occlusion hangs out (although in this style I wouldn't put heavy occlusion, and instead make it real light.)
But for consistency, I like to do my coloring with a master file open to tell me what my character looks like--so that way I can keep it looking about the same shade despite the lighting. Even then, if you have places where there's more contrast, and the skin may look lighter or darker despite being the same color as a place with less contrast. Contrast will exaggerate lightness or darkness--so in the first panel where there's a lot of contrast he seems extra pale in the shadow, compared to other places where his skin is closer to the background colors. If you want to get real particular you can just change the base color in contrasty panels if you get the sense that it doesn't read the same.
But overall I think you're doing a good job, just keep at it!
