How to combine many plots with different colors

[ggeo1]

Hello,

as i say in title,my question is how to combine many plots with different colors in one plot.

The problem is that the show command doesn't recognize the PlotStyle command.

Thank you

If you have multiple functions on the same plot, Mathematica should color them differently automatically...

Hello

I tried this

 Plot[{graph1, graph2, graph3}, {t, 0, tmax}, 
 PlotStyle -> {RGBColor[1, 0, 0], RGBColor[0, 1, 0], 
   RGBColor[0, 0, 1]}]

but it doesn't return any result.

My graph1 is

graph1 = Plot[Evaluate[FLI[t]], {t, 0, tmax}, PlotRange -> All, 
  PlotStyle -> RGBColor[0, 0.5, 1]]

but i don't know how to combine them.

Thanks

Show only combines Graphics objects, it doesn't change them.
Make your original graphs with the colors that you want, then combine with show.

If your plots are really slow to generate, then you can edit the underlying expression with a replacement rule. Eg
g1 = Plot[x^2, {x, -3, 3}]
produces the standard blue line.
g1//FullForm
shows the full expression, you see the blue is Hue[0.67, 0.6, 0.6], so you can make it red by
g1 /. Hue[0.67, 0.6, 0.6] :> RGBColor[1, 0, 0]

Ok thanks!

I used PlotStyle in every plot ,so the show command gave all three plots with their color.
