Question: how to change color of just the axis tick labels for DEplot?

is there a way to change the color of just the labels on the axis ticks only? 

I wanted to do this for DEplot, but I started with normal plot since it is easier. I could change the colors of the axis, but this changes not only the tick labels but the whole axis itself:

restart;
plot(sin(x),x=-Pi..Pi,axis=[tickmarks=[color=red]], color=blue);

So the axis itself changed color as well. It is OK for the ticks as well as the ticks labels (the numbers of the ticks). But prefer the axis itself not to be red.

Once there is a way to do the above, I wanted to apply to DEtools:-DEplot. Why? Becuase it is hard to read the Axis tick labels on DEplot. I thought that changing the color of the tick labels will it easy. But DEtools:-DEplot does not even accept axis command:

ode:= diff(y(x),x)=2*x:
DEtools:-DEplot(ode,y(x),x = -2 .. 2,y = -2 .. 2, [[0.1,0]],
               labels=["",""],
               linecolour = red,
               color = blue,
               'arrows' = 'medium',
               axesfont=['Times', 'bold', 12]
               );

You can see it is hard to read the axis tick labels above, as arrows go over some of them,. If I make them say RED, I think it will make it more clear.

Now when adding the axis options, it gives error

DEtools:-DEplot(ode,y(x),x = -2 .. 2,y = -2 .. 2, [[0.1,0]],
               linecolour = red,
               color = blue,
               arrows = MEDIUM,
               axesfont=['Times', 'bold', 10],
               axis=[tickmarks=[color=red]]
               );

Error is generated, axis is not supported command.

Any idea how to make tick labels red for DEtools:-DEplot? It will be OK if I can get both the axis and the ticks RED, at least it will be better than it is now.

One workaround way I currently use is this:

ode:= diff(y(x),x)=2*x:
p1:=DEtools:-DEplot(ode,y(x),x = -2 .. 2,y = -2 .. 2, [[0.1,0]],
               labels=["",""],
               linecolour = red,
               color = blue,
               'arrows' = 'medium'                    
               );
p2:=plot(0,x=-2..2,y=-2..2,axis=[tickmarks=[color=red]]);
plots:-display([p2,p1]);

But this seems like a hack to me. There should be a way to directly set tickmarks color in DEplot?
