Adding Color to StringForm PlotLabel

I have:

Manipulate[
If[reflection, Plot[{-func}, {x, -3, 3},
PlotStyle -> Red,
PlotRange -> {{-3, 3}, {-3, 3}},
GridLines -> Automatic,
PlotLabel -> StringForm[“f(x) = “”, -func]],
Plot[{func}, {x, -3, 3},
PlotStyle -> Blue,
PlotRange -> {{-3, 3}, {-3, 3}},
GridLines -> Automatic,
PlotLabel -> StringForm[“f(x) = “”, func]]],
{func, {Sqrt[x], Abs[x], x^2, x^3}},
{reflection, {False, True}}]

I’d like to make my plot label red when reflection is true and blue if reflection is false. How do you add color to StringForm[“f(x) = “”, func]?

You can use LabelStyle -> Directive[Bold, Red] and
LabelStyle -> Directive[Bold, Blue]

Manipulate[
If[reflection,
Plot[{-func}, {x, -3, 3}, PlotStyle -> Red,
PlotRange -> {{-3, 3}, {-3, 3}}, GridLines -> Automatic,
PlotLabel -> StringForm[“f(x) = “”, -func],
LabelStyle -> Directive[Bold, Red]],
Plot[{func}, {x, -3, 3}, PlotStyle -> Blue,
PlotRange -> {{-3, 3}, {-3, 3}}, GridLines -> Automatic,
PlotLabel -> StringForm[“f(x) = “”, func],
LabelStyle -> Directive[Bold, Blue]]], {func, {Sqrt[x], Abs[x],
x^2, x^3}}, {reflection, {False, True}}]

EDIT

Per request, changing the label and not the ticks can be done:

Individually styled labels can be used with LabelStyle and have higher
priority
-a mathematica help page

So we change the label directive to one color and wrap the label in a style, which is given priority:

If[reflection,
Plot[{-func}, {x, -3, 3}, PlotStyle -> Cyan,
PlotRange -> {{-3, 3}, {-3, 3}}, GridLines -> Automatic,
PlotLabel -> Style[StringForm[“f(x) = “”, -func], Red],
LabelStyle -> Directive[Bold, Magenta]],
Plot[{func}, {x, -3, 3},
PlotStyle -> Cyan, PlotRange -> {{-3, 3}, {-3, 3}},
GridLines -> Automatic,
PlotLabel -> Style[StringForm[“f(x) = “”, -func], Blue],
LabelStyle -> Directive[Bold, Magenta]]], {func, {Sqrt[x], Abs[x],
x^2, x^3}}, {reflection, {False, True}}]

  

 

Very easy solution. But I think I would like just my plot label to change colors and note the ticks. But thanks for a very nice easy answer.

@David also possible! check out the edits- I used outlandish colors to make each part obvious.

Thanks. These are some very nice options.
