You can combine latex paints.
It's practicable to combine paints with familiar bases such as latex, which is a aqua pattern. You can alloy leftover amounts or smaller cans of latex dye for a uniform colour in a larger size. This can be a appropriate contrivance to exercise up leftover emulsion, stretch the stain you hold and still lighten the colours of the pigmented latex paints with gray or lightly tinted latex paints. Before mixing, you should know what type of latex paints you have and mix them properly.
Instructions
1. Consult a color wheel to decide which colors the paints you have will match most closely. The shades that appear between the colors of your paint are closest to the result you will end up with. If the colors of your current paint are not primary colors (red, yellow or blue) you may end up with a neutral, earthy brown or beige.
2. Inspect the labels on your paint cans. Continue mixing for a few minutes after the color seems consistent, just to be sure the mix is complete.5. Pour the mixed paint back into the separate containers for sealed storage if you are not using them right away.
3. Pour your paints into a 5-gallon bucket.
4. Mix the paint thoroughly with a paint stir stick. Only mix exterior latex paint with other exterior latex paint. Likewise, only mix interior latex paint with other interior latex paint. Disregard the finish sheen of the paints, as the finished result will be a sheen level between the two you have. For example, a semi-gloss paint mixed with a flat paint may result in a sheen closer to an eggshell or satin finish.
