Kyle the staining that i do on all my tops are done in multiple layers, i will apply a base stain say amber with a squirt bottle and sponge depending on the effect. while the surface is still wet with the first coat i will apply a darker mahagony that is also dilute down 5:1 - 30:1 depending on the intensity than i will apply with an artist brushs and muttle in the lighter and darker veining or specialty effects. the stains also create different tones when two apposing color conflict against eachother. prior to sealing i will neutraliz the surface with a water and vinegar solution and let dry. the podium photo with the blue for example is faux finish as more a mountain stream seen but the blue area glows blue at night and fiber optics light it up in a stellar pattern. many of my recent tops are doing that. You have to be willing to experiment and push boundaries, there is always fear, but out of that you will discover amazing results. grab an old slab and start playing. there are also several concrete sights that may help gather ideas and techniques
What I did was mix two separte batches, one for each color. Then I dipped my gloves into the white and flicked it onto the form. Filled the rest with the brown and viberated. I hope that answers your questions. Thank you for the comment.
