Start with the documented color character
Soft Fern is a pale green shaded by gray. A physical comparison is needed to decide how that character works with your own finishes. Soft Fern is lighter than October Mist and Saybrook Sage, making it a useful option when the room needs less green depth.
Why the ivory upholstery and pale oak relationship matters
Ivory seating supplies a large pale neighbor; the wall should retain enough definition behind it to justify the colored paint.
Soft Fern has an LRV of 56.67; Benjamin Moore October Mist 1495 is 46.54. The difference is 10.13 points, with Soft Fern returning more light under the reference measurement. October Mist is a shaded sage that gives green a subdued starting point. This supplies a named color control; the LRV gap alone does not identify the warmer, greener or pinker paint.
Use October Mist as a control
With Soft Fern, identify the hue you want to retain rather than trying to eliminate all undertones. Place the sample with ivory upholstery and pale oak and compare October Mist. A blue-green, rosy or earthy paint may need a different color direction if its defining character is unwelcome.
Separate a persistent cast from a comparison effect
Check the wall behind the sofa in bright light; the desired fern-green should remain visible without extra green accessories. The warm-versus-cool comparison covers that related choice.
If the unwanted cast remains beside a permanent finish under normal light, that is a practical reason to replace Soft Fern. If it appears only beside an unused sample, remove the comparison and assess the intended palette alone. Before ordering samples, compare room-planning features in the paint color visualizer roundup.
