His art education continued as he attended drawing classes taught by Diogène Maillard (1840–1926) at the Gobelins tapestry factory.

[2] Luce began working in the studio of Eugène Froment [fr] (1844–1900) in 1876, producing wood-engravings for various publications, including L'Illustration and London's The Graphic.

[4] In contrast to Seurat's detached manner, Luce's paintings were passionate portrayals of contemporary subjects, depicting the "violent effects of light".

Luce joined the Société des Artistes Indépendants and participated in their third spring exhibition, where Paul Signac purchased one of his pieces, La Toilette.

[4] A New York Times critic declared this Pointillist period to be the pinnacle of Luce's artistic career, singling out the radiant 1895 painting On the Bank of the Seine at Poissy as an example.

While there, he met Les XX official Octave Maus, as well as Symbolist poet Emile Verhaeren and fellow Neo-impressionist painter Théo van Rysselberghe.

[1] Starting near the early part of the twentieth century, his identification with the Neo-impressionists began to disappear, as he became less active politically, and his artistic style shifted from Neo-impressionism, and he resumed painting in an Impressionist manner.

He most frequently created landscapes, but his other works include portraits, still lifes (especially florals), domestic scenes, such as bathers, and images of welders, rolling mill operators, and other laborers.

Many of his illustrations were featured in socialist periodicals, notably La Révolte, Jean Grave's magazine which was later called Les Temps nouveaux.

[8] On 8 July 1894, Luce, suspected of involvement in the 24 June assassination of President of France Marie François Sadi Carnot, was arrested and was confined to Mazas Prison.

[11] In 1896, while King Alfonso XIII of Spain was visiting Paris, the police detained Luce on the grounds that he was a "dangerous anarchist".

She was frequently a model for him, appearing in many of his works, often partially or fully nude, other times depicted in scenes such as on a balcony or combing her hair.

[16] Luce was among the most productive of the Neo-impressionists, creating over two thousand oil paintings, a comparably large number of watercolors, gouaches, pastels, and drawings, plus over a hundred prints.
