Check if you can experiment with the face alpha properties.

The color of pixels in a text object cannot be independently changed.

Here are some things you can try to improve the label readability.

1) Add a partially transparent label background using the backgroundColor property and a 4-element RGB value where the 4th element specifies the transparency.

h = labelpoints(x, y, labels, 'backgroundColor', [1 1 1 .5])

or make the text color partially tranparent

h = labelpoints(x, y, labels, 'Color', [1 1 1 .5])

2) Space the labels further from the lines using a larger buffer value and use NE and SW .

h1 = labelpoints(x, y, labels, 'NE', .1) % for orange line
h2 = labelpoints(x, y, labels, 'SW', .1) % for blue line
