```Hi, sorry if this showed up earlier, having some problems today.
I'm trying to set up a graphing template and am having trouble getting the arrowheads on the functions to match the colour of the functions themselves.  The last line is my arrowheads.

ClearAll["Global`*"];
Interpretation[{f = {  1/(x - 1), Sin[x], -x, x},
points = {{3, 2}, {-5, -8}}, min = -10, max = 10, size = 0.5,
rmin = -10, rmax = 10, gridx = 1, gridy = 1, hlabel = "x",
vlabel = "y"},
Panel[Grid[{{Style["Plot Characteristics", Bold], SpanFromLeft},
{"Functions:", InputField[Dynamic[f]]},
{"Points:", InputField[Dynamic[points]]},
{"Domain Min:", InputField[Dynamic[min]]},
{"Domain Max:", InputField[Dynamic[max]]},
{"Range Min:", InputField[Dynamic[rmin]]},
{"Range Max:", InputField[Dynamic[rmax]]},
{"Grid Size (cm):", InputField[Dynamic[size]]},
{"Gridline Space x:", InputField[Dynamic[gridx]]},
{"Grdiline Space y:", InputField[Dynamic[gridy]]},
{"Horizontal Label:", InputField[Dynamic[hlabel]]},
{"Vertical Label:", InputField[Dynamic[vlabel]]}
}]],
Plot[f, {x, min - 0.58*gridx, max + 0.58*gridx},
PlotRange -> {rmin - 1.01*gridy, rmax + 1.01 gridy} ,
GridLines -> {Range[min, max, gridx], Range[rmin, rmax, gridy]},
GridLinesStyle -> {{Dashed, CMYKColor[0, 0, 0, 1, 0.25],
AbsoluteThickness[0.5]}, {Dashed, CMYKColor[0, 0, 0, 1, 0.25],
AbsoluteThickness[0.5]}},
Ticks -> {Range[min, max, gridx], Range[rmin, rmax, gridy]},
TicksStyle ->
Directive[10, Opacity[0], FontOpacity -> 0.9999,
CMYKColor[0, 0, 0, 1], FontFamily -> "Helvetica"],
ImageSize -> {(max + gridx - (min - gridx))*28.52*size + 37.2 +
6.4*StringLength[hlabel], (rmax + gridy - (rmin - gridy))*28.52*
size + 49},
AspectRatio -> Full,
AxesLabel -> {Style[hlabel, Italic], Style[vlabel, Italic]},
LabelStyle -> {{FontFamily -> "Helvetica", FontSize -> 14}},
AxesStyle -> {CMYKColor[1, 1, 1, 1], AbsoluteThickness[0.5]},
PlotStyle -> {{AbsoluteThickness[1],
CMYKColor[0, 0, 0, 1]}, {AbsoluteThickness[1],
CMYKColor[0, 0.83, 1, 0]}, {AbsoluteThickness[1],
CMYKColor[1, 0, 0, 0]}, {AbsoluteThickness[1],
CMYKColor[0.36, 1, 0, 0]}, {AbsoluteThickness[1],
CMYKColor[0.63, 0, 1, 0]}, {AbsoluteThickness[1],
CMYKColor[0, 0, 0, 1]}},
Epilog -> {Arrowheads[{0.04, 0.01, {0, 0.03}}],
Arrow[{{max + gridx/2, 0}, {max + gridx/2 + gridx/10, 0}}],
Arrow[{{min - gridx/2, 0}, {min - gridx/2 - gridx/10, 0}}],
Arrow[{{0, rmax + gridy}, {0, rmax + gridy + gridy/10}}],
Arrow[{{0, rmin - gridy}, {0, rmin - gridy - gridy/10}}],
AbsolutePointSize[5], Point[points]}
]
/. Line[x__] :> Sequence[Arrowheads[{-.04, .04}], Arrow[x]]
]
