Colour rendering issue on Atom 1.28.0 / Windows 10

Prerequisites

Description

Since updating to 1.28 the colours throughout Atom are no longer rendering correctly – it appears like the gamma has been altered or something, the contrast is lower and everything is slightly lighter.

Colours are not rendering correctly even in the dev tools. Here’s two I screen-shotted from the “computed” panel:

Examining those colour squares in an image editor you can see that the colour reported as #cc6666 is actually #b36d68, and #1d1f21 is rendering as #232426.

Running with --disable-gpu does have some visible differences:

Note the render tile edges to the right. The darker area is showing the actual correct colour for the editor background.

Steps to Reproduce

n/a – Atom auto-updated, now it’s permanently in this state

Expected behavior: Colours to appear as they are defined

Actual behavior: Colours do not render as per their definitions

Reproduces how often: 100%%

Versions

Atom : 1.28.0
Electron: 2.0.3
Chrome : 61.0.3163.100
Node : 8.9.3

Additional Information

Windows 10
Nvidia GeForce GTX 1070, 398.11 drivers

Everything appears fine on my Mac, which is using the exact same editor and style configuration.

  1. Ok, well I feel pretty stupid now 😄 I did look around for a colour profile setting but not closely enough apparently. That does indeed fix it, thanks!
